Best video I’ve seen all decade
You need to watch more videos.
Good to see some content! Been awhile!
Yes it has, planning on putting out regular LS related content again on a regular basis. Thanks for being there from pretty much the beginning!
Nice work 😊
Thank you for the review I have been considering getting this exact harness you just got your self a new subscriber
Good to hear, thanks for subscribing!

How is the harness now few months later? Did it work well?
Thank you for this info
You’re welcome, thanks for watching and commenting!
A builder put one of those in my 6.0 4l80e swap.....it's getting yanked no O2 sensors and it caused shift issues. PSI also seals the wires into the PCM.
I just bought a psi harness for multec injectors and 4l60e for 98 bucks and it’s working perfectly. I did get the plastic wrapping and it’s looks really cheap .
any links to the harness?
I know I’m late for this video, but I know a guy that uses only these harnesses. I’m gonna watch your video again so I can catch the guy name you said build harnesses. I’m a cheapo but I also know that it’s important to at least have good wires.
Awesome thank you. Where can I get a harness by Nathan?
I ordered the same harness an never got any instructions lol does anyone possible have a picture of the manual they sent for the under dash wires
Also. The wires that don’t have the same color. Is it a problem with the vehicle operating, or not that big of a deal.
I had this exact harness saved in my watchlist on ebay and they through me an offer of $159.99 and I couldnt pass it up! Just got it running yesterday and so far so good, I just have to figure out how to hook into it to log my Wideband O2 sensor with Hptuners.
I’ve had a bit of a problem on my harness because when I plug in the 02 sensors, it runs just awful.
@@MrGto05 mine has been working great, you sure its the harness and no the tune or sensor? a data log might help you se whats going on. As for me im really wishing i would have just went with a holley setup to begin with since im boosted, After buying a wideband sensor, 2 step controller, unlocking the PCm and spending countess hours learning to half way tune with HP tuners Im in it just as much as a Terminator X would have cost.
Hello, I have one of Nathans harness for a 2003 5.3, no trans and I cant figure his instructions for the Underdash wires. I tried to talk to him but his Google translate isnt very good. Can you help? Brown wire goes where? Black says Speedo on Module? White says Tach, thats basic. Im not using his 2 fan wires. orange says park Neutral, description says To Ground in Park or Neutral? Purple says Brake signal to 12v Brake not apply??? Im not using Grey or Pink, Multiple Black wire, chassis ground, basic. Red Fuel pump relays, should just go to 12v key on? Also has a Black/Red wire that has "Tacho" on it, not sure if that is the same as White Tach wire? Thanks for any help!
Did you ever got that harness installed?
Ordered a Nathan Wei harness and the o2 sensors were not hooked up correctly. I haven't check the tach wire but I have a feeling that's wrong as well because it's not reading correctly after hooking it up. Just found out the map sensor might be wrong also...for 300 bucks I could of just paid another 200 and got the psi harness or a BP automotive one. Or just bought the $80 ebay harness and rewire it myself be4 I hooked it up... 4/10 would not recommend.
I'm going to use the factory harness for my swap. Planning on removing what I don't need.
That’s definitely a good option if you’ve got the time and are on a tight budget. LT1swap.com has great info to help with that.
Who did you contact in China? How do I get in touch with them?
Did you find the extended length was necessary or would it have made it under the dash without it? Also, the two red wires that tie to the starter, are they fused at near the ends (hard to see)? You’d really want a fuse near that starter connection.
I don’t have it installed yet but I think the extra length will be necessary. The power wires aren’t fused but that is a good point, I plan on installing either fuses or fusible links near the starter connection to protect the main power leads. I also will have my hands on an American made harness for comparison soon.
@@LowbuckLS Thanks. I look forward to hearing your comparison. I’m strongly considering one of Nathan’s harnesses. One American harness I saw had fusible links built-in near the starter, so I was curious about that. I’m interested in the authenticity/quality of the connectors compared to others, too.
Now we need to see a revealing video on what project this harness is going :)
Will have more content soon but it will be going on the 6.0L LQ4 that will be going into my Suburban
@@LowbuckLS hmmmm, the power plant of the suburban would look really good in my 1971 cutlass S :)
To use this harness with Drive by Wire would I just need a DBW pedal or would I still need the additional module (you can tell I'm new to all this)? Have LQ4 6.0 DBW engine/ECU that's going into a 71 Nova.
Yes you’ll still need a DBW pedal and TAC module
What about an oil sending unit wire
The oil pressure sensor doesn’t come back to the PCM on these Gen 3 engines, it goes to the body control module and dash/gauge
@@LowbuckLS good to know I’m looking to get vats and egr flashed out of my pcm or ecm what does it cost and where do I send it I’m in the middle of teaching myself how to do the flashing myself making a harness do I need a 12 volt 500 mv power supply I found a patch cord with cat 5/6 on one end and obd 2 on other end hoping it will work
@@briang1247 if you wanted me to reflash it, I charge $100 and you’d have to ship to me up in Canada, takes about a week each way from most places in the US.
@@LowbuckLS where about in Canada I live in Saskatchewan
He never tests them to see if they work
