    ok
    here we go
    here is the are i am looking, there are 3 pictures.
    i follow the TPS wires down where it meets up then i cut away the tape/loom from the grommet past the TPS wires and about 3 more inches for good measure, still cant find anything.


    if it makes a difference it is a 1992
    i was hoping to find it here so i dont have to run wire all over to the VAF but i can run it to the VAF if need be.... but would rather not.

    here are some pictures that i wrote on, hopefully you can see my notes...
    i tried one wire that is green with a faded looking red tracer, it did not appear to have continuity to the green with red tracer at the VAF.

    the one i pointed to in the last photo?
    i saw the light green with red at the VAF, but i cant find a match in the loom.
    does the key have to be on for continuity?

    I finally got a chance to look at how I wired mine up, after 2 days of rain. The LG/R wire is in the harness that runs above the brake booster. If you follow it down there is a "Y" near the wiper motor. You will need to run a jumper wire from that area to go to where the rest of the TPS wires are spliced together. Sorry about the confusion, but I have worked on a couple hundred cars since I did this mod, and couldn't remember exactly how I did it.

    got it done yay!
    those last pics really helped a lot! i was in the completely wrong area.
    i found the GR/R wire right away when i opened the harness over the brake booster. open it wherever is convenient. them i spliced into the wires for the 3 wire tps, and left the connector on, that way if i ever need to go back i can without more wiring.
    i spent more time scraping the gasket and hooking up the coolant hoses than i did wiring and bolting the TB


    thanks to everyone who helped!

    here is to better MPGs

    This is helping me as well. Just one quit question will the 4 wire tps and throttle body from a SOHC protege be the same as the egt one?

    Bringing a dead post back to life, in regards to wiring into vaf, and not having to move any pins on the ecu, I would have to move the required pins on a bp26 ecu though wouldn't I?

    The need to dig into the wiring harnesses of fuel injected cars -at all- gives me nightmares!
