Please help me get her back on the road
I have TBI 350/4L80E that I pulled from a 95 GMC Vandura 3500.I am in the process of putting this combo in my 72 Burb.I have the complete wiring harness and ECM still attached to the motor/trans combo.This is where I need help.I can do all the mechanical stuff no problem.....the electrical is where I am going to be lost.Has anyone on this site done this swap before keeping the fuel injection and ele. controlled trans?If one of yall knows how to do this, or have done it, can yall please help me out.Is there a Faq thread for this?

Re: Please help me get her back on the road
I did the exact same thing in my 72 Suburban. I used the running gear out of an 89 Suburban. What helped me was I used the entire harness front to rear and only patched in the gauges. Now...with that said....Im pretty handy electrically.....and I WILL NEVER DO IT AGAIN!
I didnt have many problems but it took forever! I had the wiring diagram from the 89 and the 72 side by side and I sat ther and crossed everything over. It ended up being about a day per circuit becuase i had to walk away after each one. If I were to ever try that again I woul;d save the hours and hours and find a pre-made harness for that application.

Re: Please help me get her back on the road
What did you end up doing for the gauges in the dash?There are a lot of wires I'm sure I wont be using in the Burb.How do I terminate these wires with out messing up the ecm?Do you have any pics?Do you still have the wire diagrams for both?Where did you fing the 89 wire diagram so I can find one for the van harness?I just got done pulling the under dash harness and fuse box from the van.72Freak,thanks for your help in advance

ECM worked fine..i dont recall any issues but it was a very early SIMPLE one. There may had been a speed sensor issue because of the old style speedo. SOLUTION for your application unknown. NO PICS...sorry...its since been sold. Wiring diagrams were in the Chilton style manuals and factory service manual.

Re: Please help me get her back on the road
I have not used a stock vehicle harness with an electronic transmission. My guess is though, that when you boil it all down, if you use the modern harness complete that you will really only hook up power and ground. All the VSS, temperature, throttle position, MAP sensor, etc is all self contained in the harness. Since it is 95, you are still OBD1 so you don’t have to worry about oxygen sensors, fuel tank pressure sensors, and the like. You can use “old” sending units to drive original gauges and leave all that alone. You can look at jagsthatrun.com for info on how to get a mechanical speedo output on an electronic trans-or just have your speedo converted to electronic.
If you try to use the van harness complete and replace the truck harness, it can probably be done. You will have to change ignition switch wiring, can probably use turn signal wiring, have to move hi-low headlight switch, have to heavily modify heater and/or A/C wiring, radio no big deal, fusebox hole is different, you will need to have your speedometer converted to electronic and ammeter converted to voltmeter (the original shunt ammeter won’t handle high amps), headlight switch wiring in cab is same, dome light easily integrated. I would integrate the taillight harnesses together. The engine compartment on the lighting side, I would splice the truck front to the van harness. The engine harness on engine side is OK. The rest of the swap is like any fuel injection/OD trans swap, finding a place for the ECM, fuel tank and lines, trans mount, driveshaft, etc. Here is a post on a TPI swap, much of the basics are similar to a TBI swap. http://67-72chevytrucks.com/vboard/s...=239354&page=2

Re: Please help me get her back on the road
The harness you linked for me says its for 82-93.Trans:2004r,700r4 and other non-electronic.Do you know of one that would work with the 4L80E I have?The money does seem well worth avoiding frustrating days in the Texas heat.

Re: Please help me get her back on the road
To me this is a bit too harsh. I have done a number of FI swaps using stock harness, just never done one that controlled the transmission too or tried to use it to replace the stock harness. I'm willing to bet that if you took the whole harness and unwrapped it and just kept what was needed for the engine and transmission that you will end up with just power and grounds. I know this is the case on Ford stuff, and earler TBI van. I have a 3.1 Cavilier harness that I am going to modify if I ever do another TPI conversion. Just have to add 2 injector leads and move a few wires around from what I can see. If you are good with electrical stuff, I would see this as a challenge. If you do buy a harness, I would not buy a Painless. IMHO the fit and finish is less than adequate. I have used them for street rod type rewires and if you do your own wrapping and finishing they work fine, but they come to you with small nylon tie-wraps every few inches instead of loom. For a FI harness they also use smaller gauge wire than original. Just my .02

Re: Please help me get her back on the road
This is actually how we started the project....trying to pull out or isolate only what we needed. I was more of a nighmare than using the entire harness. As mentioned above by myself and others....its really going to come down to a time V/S money thing. When I did mine I had way more time than money and after doing it was NOT worth it for ME. There are so many products on the market now to do just what he is trying that were NOT on the market when I did mine and the prices are not unreasonable.. I think it is also a personality thing. If you are patient, mithodical, technical and have the time...its a great challenge.

Re: Please help me get her back on the road
Looks like you can buy a Howell harness for the TBI/4L80E trans for $400. See http://howellefi.com/gm-tbi-products...sses-only.html
p/n H9395 at the bottom of the page They make a super quality harness and will work with you if you need custom lengths or want fans, etc. If you don't want to deal with the stock harness, then this is the direction I would go. I will concede that for $400 it may not be worth the hassle of taking a stock one apart.
