Got to love the man who doesn’t realise the complications he’s creating, and just gets on solving the problems.
Absolutely
You say that he is like gov ? Creates a problem and than solves it creating another 2 ?
a little tip you should stagger your hole in the door to the a pillar for your wiring so when the door is shut the wiring folds a little leaving the holes at the same height the wiring wants to push and pull through the holes have a look at any car you will see that the rubber tube between door and pillar is staggered apart from that i really love both builds keep up the great work jeff
Those firewall standoffs have got to be the coolest thing I’ve seen in a while! Sorry for being late but loving the content.
Best channel on YT, truly, madly, alfarrari.
@SuperfastMatt is also doing great work, love his humor and his "hail the algorithm" saying, also his engineering approach on many topics are great! Yes, it's looking good Jeff, happy for you!
Now that I've seen a close up of the great grill work, tuck a 3D printed outline of a Ferrari prancing horse in black behind the Alfa center grill.
Make it slightly different than the Ferrari Prancing Horse- Enzo's relatives seem as fanatic about their Brand as ever! FR
mrs Jeff"s outtakes is the best for sure
Well thought out and resolved, as usual. Super fast Matt is definitely on the money. However, it’d be hard to build better looms than the Binky boys! Good luck, Jeff, but I hope you don’t over complicate your build; there’s something to be said for simplicity sometimes.
Make sure you have fused links for the AC unit, a resetable trip would be a good idea as well. They draw a lot of amps so short wires are a good idea, so your placement is good.
I have a Moto gadget M on one of my motorcycles. Great unit. The only thing I would suggest is you put a fuse or circuit breaker on the power lead to the unit. You can still fry the unit if it isn’t protected. Otherwise, great choice. They are an awesome unit.
Agreed, I put a 30A fuse on my Moto Guzzi project, between the battery and the m-unit.
@@davidburne9477 did the same only I used the blade type circuit breaker that fits into the fuse holder.
Tip
Wood is your friend
When you need to mock up things in position to run wires and ensure that there is no interference and to weld in brackets you don’t really want to be doing all this with some heavy or very expensive components that you might not be able to replace easily.
So before risking it mock it.
Make a mock version out of scrap bits of wood and or cardboard. Then it won’t matter if you accidentally put a drill into it or something.
Great work so far, i wouldn't run thr AC line's through the interior as they attract a lot of moisture and you'll end up with damp carpets and eventually corrosion
Excited every week to see your progress. Keep making progresss!
I’m so impressed with the efforts you’ve taken, all of it comes together so well. Youre an automotive builder and an artist; one of the greats!
Lithium battery works really well on cars that sit for long periods. Only 6 lbs. small and sealed. Can fit behind seat. Shorten heavy batt cable. Can be bolted in with strap on over ground eliminating heavy ground strap. Use type with internal shut down to prevent battery from drawing down to low. Has button for start if battery is drained and off. Prevents damage to battery.
As an owner of a GTV, we spend more time building, restoring, maintaining and repairing these cars than actually driving them.
Another great episode Jeff, coming along nicely 👍
This is exactly what I used on my custom chopper love it and I will use it on my karman ghia project also, I also like you link ecu selection!!!
Make the Noise! Binky is proud 👍
Sei il migliore ingegnere del mondo bravissimo improvvisatore.
i have done this on my ecotec conversion to my alfa romeo spider.. to keep it simple, and easy to work with keep the body wiring i/e/ lights heater fan. power window..separate from the engine ecu harness.. so 2 harnesses.. one for the basic body.. another for the engine ecu...worked great on my car.. lightweight harnesses.. and i can remove them if in need to repair them( if ever ) separately...and because all my light now are LED's i can run much smaller wire to the brake lights/ running lights etc.
Another great video. I have found it is easier to break down the loom with connections. It makes installing it simpler, and if there are any problems a lot better than trying replace parts
Also gives access for future testing points for diagnosing issues without piercing the insulation.
Amazing work as usual Jeff
Love the face of this car. Love what you do for the Electric lines. Bruno from France.
That rope idea is genius!
Man I just noticed the alfarrari emblem you designed on your shirt. The snake head with the crown on the Ferrari stallion is dope bro.
That grill looks fantastic!!
I like how you are doing it can't wait to see you driving it
A tip to easily create your wiring loom: get a flat surface (white board is ideal but a wall or a floor will do too). It has to be big enough to draw the outlines of your car on. Also draw all the electric devices in the car at their actual locations and all the panels were your loom has to go through. Then you can draw a lifesize wiring diagram, this way it's easy to get the measurements of every single wire without having to struggle with it inside the car. Then you can build your loom on to this "diagram". It'll also be easy to wrap the loom knowing exactly were every single wire splits of and to see were you need to mold in any bends for perfect fitment ( Do remember to add extra wire were the loom connects with a device that's not at the same height as the loom 😁).
The rope is the best way to get everything in the correct spot.
Gotta love a man that puts a Ferrari engine in his car then buys a cheap PDM. A full-blown PDM (I’m fitting the PDM32 from AIM) will integrate with your ECU and simplify a load of the jobs that you’re going to have to overcome. I know it’s not cheap but it will do all of the jobs properly. Ironically, had you simply rewired the original Alfa, your PDM might have been a good option, but, with all of the gizmos you’ve added, it will barely scratch the surface.
Love that momo steering wheel, had one with no ferrari logo on my first car so many memories!!!!!
Good progress again👍 wish I had heard of that PDM a few months ago when making my harness looks a lot neater option, may even look to redo my wiring in the future
But it will require a big lot of relays- all of which are in the Audi he parted for the Boxster's engine- and all the circuits are already there, as well as relays and connectors made by and for VW. FR
Looking to the future, if you're going to be making more 3D printed parts, consider pre-buying some "SL Type" heat set threaded brass inserts. The channel "CNC Kitchen" has a great video on them. You just model an appropriately sized hole in your part, then push the insert in with a soldering iron. Gives you a strong, durable, and reusable way to fasten 3D printed parts to the car, or fasten things to 3D printed parts.
I bought an aftermarket Bluetooth module for my car that has exactly that. They’re plenty strong enough for wiring/computers, haven’t used them anywhere else just yet though
Interesting I haven't seen that, but I will have a look. Thanks.
@@HomeBuiltByJeff Jeff with the amount of cable and tubes going through the car would it not have been better to run 2 conduits, 1 ether side of the car but underneath, entering the boot from under the car that way you can have wires one side vanishing and the same with flexable pipe work
Good luck! It took me weeks this spring to make a loom for my Giulia racecar.
For Mrs Jeff, the Alfa Golden Arrow 1948. Classic car
Jeff’s chuckle during the Mrs Jeff segment was great! I’m glad you didn’t have edit it out!
I know it's too late to redo, but for your future projects, I have done a fair amount of rewires where I placed the fuse box and modules on the back wall or sides of the trunk (boot) for easier access. Some of the older owners had no wish to climb under a dash to replace a bad fuse or relay. Keep up the great work.
Bueller, Bueller, Bueller, Bueller.... One of my all time favs also!
I also love my 3d Printer! I have made shift knobs, emblems, radio knobs, and a Tachometer! Though I have yet to make a real video about it yet, largely because I am trying to catch up on my videos back from March!
Good choice on the m unit pdm.
Heatshrink label maker will be super handy too. Dymo 4200 is a great affordable unit at about 140 from officeworks
Might be too late, but when you run wires from the car into the door go one hole low and one hole high.
Have a look at where you have your rope when you opena and close the door and you'll see the rope bends and can kink. Over time it will fatigue the wire.
If you go one low and one high the wire will twist instead and not fatigue. If you can get them far enough apart it won't even make a difference to the wire.
If you've got one of those cheap central wiring kits the big bulky wire won't even close in the door
I always wondered how long a piece of string was, and Jeff has helped me out.l😀
How many times do you want to say basic?
Jeff: Yes
I have the exact PDM for my CX500. Awesome piece of kit.
left turn, right turn, running lights, high beam, low beam, ground, a six wire plug, front lighting done.
Using the motogadget m-unit on my Moto Guzzi cafe project. Pretty straightforward. Eliminates relays etc as well. Bluetooth programmability is quite useful. It also doesn’t complain about adding LED indicators and headlight etc like some factory modules do.
Awesome 👍🏻👏👏 Ferries Buellers day off is my favorite movie to 😀 loved the car 😻🤙🏼
Fun fact for Mrs Jeff - the Ferrari Daytona Spyder Don Johnson drove in Miami Vice was also a kit car. Btw i miss the old Mrs Jeff music. Call me old, call me sad….
The stand off brackets are a simple solution! I dreaded putting holes/riv nuts in places before knowing I’m introducing moisture. This obviously both gives you a mounting location and keeps the water outside where it belongs. Here it maintains a tidy fire wall as well.
SEI MAGNIFICO
I'm famous now! Cheers for the mention mate,you made my week!
Haha. Thanks for the help mate :D
@@HomeBuiltByJeff where can I find one of these motorcycle PDMs
@@phillipnorth3428 Don't If I did it again I would get a proper PDM
Just loving this build. Everytime I see the new grill though, I wonder if it could look even better with a single horizontal bar (between the badge and headlights) similar to some of the 1750 GTV's? Beautiful car whichever way you go with it and as you rightly say, if it's worth doing, it's worth doing twice (at least 😁)
“A hole lot of work…” I see what you did there Jeff 👍🏼👍🏼😂😂😂
3d printing is a whole new dimension of manufacturing. I still "forget" that i have it, and more than once had a "dude, you now have a printer, you can do it yourself" moment.
On some old Fiats I've scraped (Panda, Ducato) the wiring into the back ran over the A-pillars, roof and C-pillars.
Make a nice, carpeted parcel shelf where the rear seals would be, and add a front lip to keep things from sliding. Maybe even tie-down/cargo net anchor points to secure items. Build it at tunnel height so 1) you have a nice flat surface, and 2) you have a gap underneath to run all those rear wires.
The grille looks amazing!
The wiring looks like it will turn out well, good planning is key! I like the pipe "shortcuts", should make the AC lines far more manageable.
One piece of advice, the way you set up the holes in the door/door jamb right next to each other will break the wiring rather quickly as it continually bends and slightly stretches in the same spot.
The way many OEM's does it is to have the holes 100mm-200mm apart, one hole further up than the other, making a length of the loom run colinearly with the hinges. This spreads the motion out over a greater length of the loom, and allows the wiring to twist instead of bend.
I've tried it both ways when running speaker and power lock wiring to the doors of my 1979 Opel Kadett C. First try was with the holes right next to each other, and the wires broke with less than 2 months of use. Second try, with about 140mm of height difference between the hole in the jamb and door is still going strong, years later.
Good point.
@@HomeBuiltByJeff go lower on the door, higher on the body, that way water can't run down and into the car, worst case it goes into the door and out the drain holes (assuming it has some/you put some in)
Ouu Man is this like episode no 1000
Just kiding, nice work
The mesh grill looks amazing. A perfect fit! I wonder what color the car will be painted in … classic Alfa red or maybe dark blue? It will be a stunner either way 👍
I think it will be dark green :+
Don’t go cliched Alfa red. - though hard to think what would be a good alternative!
Certainly not the avocado colour which was so popular back in the day
The Alfa Montreal's came out in a beautiful green. 😻
Have no need to ever know this information but Link have nailed product placement. It would be my go-to if I woke up on a desert island without an ECU.
Life moves pretty fast.If you don't stop and look around once in a while, you could miss it! Keep up the great work mate...
I hope you considered that you can get correct CCA battery in this size.
Also regarding PDM and wiring as a whole:
1. Cars are generally 12V, but circuits divide into low amperage and high amperage. In low amperage circuits you might get away with built in protection of PDM, but in case of failure of high amperage circuit it might burn down whole car electronics to the ground. I hope you considered at least protecting PDM power supply with fuses.
2. Switching high amperage loads and with loads of transients is highly ineffective with solid state electronics. In addition most of solid state switches doesn't offer electrical seperation between circuits. Weird interference issues might be real PITA to track down.
Have you thought about playing around with remaking the original center grill piece, in the same mesh design that you used the 3d printer to make those awesome grill pieces as well? If it does'nt look good, then you'll always have the nice original piece to use :)
Love all your builds, and it amazing to see how far your skillset have come since the start of Harry. Cheers from Denmark!
wired from scratch many fiberglass rebuilt jeeps, two hours all the basic wiring can be ready for plugs.
BUEN TRABAJO AMIGO
Much neater battery clamp is to use the angled sections on bottom the battery as some car makers do.
As soon as you mentioned fusebox i thought should use a pdm much better then you produced one great job love the outro clips with Mrs Jeff.
Very nice 👍🏼
It looks great with the fender flares removed.
Yes! Mrs Jeff!
Love the copper colour of the grills you made wonder how would look if the centre piece was same colour……
The original duel ECU setup is interesting. Often times in aviation you see duel ECUs and sometimes each running have the cylinders.
Alerta wiring is coming😭👍🤯i LOVE this build...
I’m gunah steal your rope idea
Note.
Many batteries have a ridge around the base that can be used to clamp the battery down so you don’t need the strap to go over the top.
Unless you’re off road racing clamping the base is more than good enough for the job.
Moving right along! nice tease for things to come. Mr Jeff is especially jazzed on this project.
No waaay she gets to drive this monster. or? o0
Better throw a 2 liter pancake motor in the bug. ;-)
It's cool with 3d Print and nice If you use it and a next very good Job is done by the jeff's very top ⭐❤️💙👍
bro looks like anotheer binky project ahahhaah
I expected you to mare a larger false rear tunnel to hide the wiring, you could have also balanced the console centrally at the same time?
Maybe you still could and make a feature of it, make it removable and painted to match?
I believe the bonnet scoop in those 250 GT California vehicles is an affectation, and does not open into the engine bay.
Watching this video makes me appreciate that I can purchase a complete ready made harness for my '59 Sprite project. Have you been working with an engineer as you go along with the car? I'd hate to think that you get it all done, then fail whatever inspections you have to do and have to go back and redo a bunch of stuff.
🇮🇹👍👍👍merci mr Jeff pour cette vidéo
Yes m.unit!
An entire loom from scratch. Eek! But Jeff's indomitable as ever. I can't get my head around how the electric aircon will work though, I'd have thought the compressor is at least a kW and that you'd need a huge alternator to power it (at least in traffic). Apropos the current draw, I wonder if an auxliary/parallel li-ion battery could be used? There are quite a few 'abstracts' and 'white papers' covering the design of systems for vehicles (cars, boats, aircraft) but I haven't found anything in the way of kits for one-offs.
Classic Retrofit ;)
Thought you might enjoy this weeks U tube video from Harry's garage Porche 911 .
The drivers side sill panel looks like it would have been a perfect place to hide the wiring through, at least from what I can see in the video.
Yes, it is very strange that he has overlooked the sills (LH side is where the A/C unit will be).
Don’t forget interior lighting. Though no one needs a map reading light these days
That aircon unit is going to draw at least 50 amps. Is the alternator big enough to run it and all the other systems on the car ?
That m-unit looks cool! Might consider it for my RE Capella. How would it handle the headlights though, current wise? My car has 2 x low beam, 4 x hi beam.
Hey Jeff - any chance you can post a link to the PDM - also still loving the grill - can't wait to see it on the finished front end. 👍
Search for the m-unit blue
I think I go for Motogadget bluetooth on my 1980 Moto Guzzi 850 LeMans 2 and very expensieve parts such as mirrors switches etc but nice plan on paper !
Would love to know where you got the motorcycle pdm from, post in a link please!
Yes! I've finally caught up all the videos!
Jeff - where'd you get the PDM from?
Nice work. The pdu sounds quite interesting. Im looking for something like that to my racecar. Can you post a link to the one youve got?
If your still wondering its the Motogadget m-Unit Basic Digital Control And Fuse Box
Rolf Harris didn't kill himself 👍
That pdm looks sooo great, where can i find one with world wide shipping? 😬
@Home Built By Jeff any details on that PDM module?
i have to do this for my Austin Healey and im scared lol but thanks for the info
Love your work. But just a thought, I'd run the wiring along the tunnel then away from it to the side of the car before heading under the floor pan, so in the unfortunate situation you blow a driveshaft it won't rip the wiring apart and set the thing on fire. May be an engineering requirement too but not sure
EDIT: jumped the gun on this one and see you went over the rear seat rise bits and into back. Sorted.
Also if you need a nice mount laser cut and folded for the Link I have a laser cutter and can cut and send it, if you can draw it.
