What did you pull this from ?

You're awesome brother

The best TBI wiring video I totally understand your anger I have a TBI 350 ion 81 Trans am

Chop your rhubarb in about 1 inch pieces before freezing. Not hard. Not a lot of work. Not very time consuming. This is the lazy man's method in this video.

Old video but i am researching a tbi swap on my Jeep J10 with an AMC 360. Watching this gives me hope that it is pretty straightforward and can be done easily. Im going to make a ford spreadbore to gm tbi adapter out of s chunk of aluminum and will be pulling everything needed from the salvage yard. I will also be swapping to the newer motorcraft distributor and gm hei module. Have you had any issues with it since doing the swap? Also how is the performance? I dont expect to gain power but do expect better throttle response, better mpg, and just run better.

That's a good looking boat for what I can see.

Do you have the diagram?

This is the only video on here that tells me how to make my injectors work on my 88 K5. Thanks a lot.

The jammed on battery connector, lol is that for theft prevention?

Howd ya get the throttle cable to hook up? Ive got a dodge truck with a 1975 holley 2245 2bbl carb. No friggin clue on how to hook it up!!

Could you please share the info about the wires that need to be grounded? I'm working in this swap but I don't have any idea about grounds...

please for the love of god it's not that complicated only need 4 wires get rid of the rest

have a question on the schematics I have it shows the c9 wire goes to the starter solenoid and the fuel pump wire is the green with white wire or the A1 wire?

did u find which wires are for the check engine light?

on the other video u show jumping the ignition to the power. is that still needed so the injectors will fire?

Nope. I had a local guy build me one at his shop using autocad

Did you make your own TBI to 2bbl adapter? I saw Howell sells one for $80 but was hoping to make one for free.

Fkn brilliant. I'm gonna go get em now.

Thanks for the post ill refer to this when I do my 80 cj7 258

well fuck. that's an awesome explanation on this setup and shit

Awesome, Thanks Jason. Getting ready to do this on my 88 YJ. I have ECM and throttle body and most sensors. Going the JY to try and find an unmolested wiring harness from an Astro van, S-10 or full size C/K with a 4.3. Jason, what did you use for a fuel pump? Did you use one of those aftermarket pumps like Mr. Gasket of another pump? Thanks

It works good, but you need a heated O2 sensor on aftermarket headers if you are locating it downstream from the head. If you have a spot for it in the stock exhaust near the manifold, the stock O2 sensor should work fine. I'm now fixing up my Megasquirt tbi system for it. Total cost of a general chevy tbi swap is about $50-$80 in salvage yard parts (ECM unit, throttle body, sensors, wiring, etc), a $40 electric fuel line pump, $150 in new fuel injectors or at least good used ones that you know work, and another $50 for new sensors and other bits if the junkyard parts don't work or you want to buy some of the parts new.

Just curious what was the cost not including new parts? Thanks

Hello, jason, great write up, i need your help, why ypu connect the c9 purple solenoid signal to tach wire? why not in the starter solenoid? regards

Wow I have a 454 and I am so excited to see you because I was trying to do this already so you inspired me I'm going to go get the kid from the junkyard and do everything you just show me to do but imma do it for my 454 thank you imma keep you updated on my project and if I get stuck would you give me feedback right now it is a 1986 Buick Regal with a 454 in it from k5 blazer

Manual transmission. 3 speed T-150.

Did you use a manual trans or automatic ECU?

Hi Jason! I just switched out my carb and installed a rebuilt gm throttle body with rebuild ecm etc.. My cj7 isn't running very well... :( All of the wires are correct. Have a ground wire to the battery. Just wondering where you hooked your 12volt source? I put on the positive side of the coil.. Would that take power away from my ignition source and cause a weak boggy running jeep? :-0 My check engine light is illuminating too.. But its for the 42 and 43.. Electric spark control --which I haven't installed.. Don't know if this would be the issue? PS. Your jeep is running better than mine.. :(

You’ll need to go to a junk yard and pull the tbi with injector plate off of a 350 engine. Pick a truck if you can, because it’s likely that you’ll get the tbi computer that has the “734” numbers on it that works best with the truck/jeep tbi conversion. Make sure you find a wiring harness that has most, if not all of the sensor connectors intact. Your sensor connector priority should be for the Coolant sensor, fuel injector connectors, O2 sensor, throttle sensor, idle air control sensor, and especially the wires going to the tbi computer. Make sure to clean up the TBI as well as you can. You should buy a new coolant sensor and fuel injectors. I tried to save money by using the old fuel injectors and cleaning them and they had shorts in them and fried my aftermarket Mega Squirt controller. Buy new injectors and it’ll make it all easier.

Do you have a parts list for everything that you used for this conversion. Ready to do it, just need to start getting all the parts. What can you pull a throttle body off of? What should be ordered new?

That was fuckin great! Been lookin for info on a basic hookup on the TBI swap...Thank's!

The adapter plate worked great, had my local machine shop guy design and build one up for me. Turns out that I didn't need the tach filter since I had the after market GM style HEI distributor and wasn't using points or a weaker type of HEI distributor.

I had my local machine shop guy design an adapter for my set up out of aluminum plating to fit the Clifford intake on mine. He probably still has it saved in his autocad program if you would like me to relay his contact information. Otherwise, I would just suggest that you look at having your local machine shop make you an adapter plate for your set up.

Might have to either make something out of an aluminum plate or maybe see if there's anything on eBay... You would have to know what style of base your carb has, I'm pretty sure a good machine shop could fab one up. I'm not very familiar with the Jeep engines/carbs.

It's working great. The only problem I have is that it is now running a little rich, which I think is due to the fact that my narrow band O2 sensor is ran so far downstream that I need to buy a heated one to work properly. I pulled my boat to the lake several times already this summer with it and it started up and ran fine, so yes, I'd recommend the swap, but only if you buy new fuel injectors for the junkyard tbi.

Thanks for posting this.

If you're not using a GM 8-pin ignition module and computer controlled timing you will need a tach adapter. The tach signal from an old style HEI distributor isn't a clean enough signal to make the ECU fire the injectors.

Go Jason Go!!

I've fermented batches on average about 3 months, but some I've fermented for well over a year before killing the yeast.

how long is your avrage fermentation time i made a batch and its been fermenting since august 4th
