Im piecing back together a 85 turbo 1 gbody engine bay harness that was modified to run on a 86/87 glhs t2 lm. I seem to have all the wiring, but im sure i dont have things hooked up right. First thing i dont know is if this should have a 1 wire o2 sensor or a 3 wire. And if its a 3 wire im not sure how to wire it in. Next is the map has been moved from the LM to under the hood. Its been wired into the lm plugs and im not sure whats correct or not. The motor runs, but very poorly. Then i gotta start building a vacuum harness to attach to all the appropriate sensors. I bought an aftermarket vacuum block and started connecting stuff. Im honestly unsure what is supposed to have its own dedicated vacuum source and what could possibly share by way of a tee. I have a haynes manual and a chrysler tech manual but neither is for a glhs unfortunately. If you can get a good deal from Target Ad, never miss that.
