Removing TBI harness from a truck

[Stomis]

So I sold my TBI setup to a member here. Ive got the whole harness out except the fuel pump stretch and a small piece under the dash.

This small extension under the dash is what Im curious about. Its 6 leads and feature a great pumpkin orange wire. I believe only 5 of the 6 leads are actually occupied. It stretches from the main fuel injection harness over the HVAC box by the brain over to the gauge cluster. What the F is in it? Is it necessary?

All I can think of is check engine light.


Further more I want to make this as easy as possible for the buyer. Less headaches he has on install equals less headaches for me to because Im not gonna leave him flat.

I unplugged the main power from the fuse block. Will he be able to plug this into a pre-fuel injection fuse block or should I yank the block out and give it to him also?

I'd send him the whole damn harness and gauge cluster , gives him more to work with

I plan on giving him more than he needs. Only thing I dont plan on sending him so far is the HVAC harness and headlight harness.

Yep good plan, its easy to toss what you dont need but hard to make what you do need

Ah I just figured out what it was, Shower epiphany. Check engine light and diagnostic plug.

Ohh i'm excited to get this in the mail! Thanks for putting the time into doing this right! Good seller right here. I hope this plugs pretty easy into my car since I have a CCC quadrajet already in there with the ecm and the 02 bung already in place plus a lot of the sensors.

As of right now the only thing your going to have to scratch wire is the o2 sensor and thats because these trucks never came with 3 wire sensors. But thats simple, signal/ground/ign hot.
