91 GTP 3.4l 5 speed engine wiring harness

Yes you can. My 92 was originally an auto car and I put a 5 speed in its place because I got tired of changing transmissions. The VSS wire is on the passenger side on the auto. The harness needs to have the snake-skin removed and move the sensor plug to the drivers side. IIRC, the VSS plug on the manual is the same as the auto. Also, the purple and yellow wires on the P-N safety switch need soldered together (those are for the starter). There are also two other wires in there (Orange and Light Green), those solder to the pigtail you will cut off of your 5 speed harness for your reverse lights- polarity on it really doesn't matter. Also connect the Green/Black wire to the Orange wire so your trunk popper works (it hooks into the P/N switch so you can't pop your trunk while going down the highway on accident).Also the Tan/Black wire from the transmission control plug needs to run to your shift light (or B-7 on the White plug on the ECM) which is something I didn't do.

I have hit a few yards and there are a few 3.4l GTP's out there, but I have been limiting my search to the ones with manual transmissions, as rare as they are I have had no luck. Could I pull one with an automatic trans and somehow mod it to work with my man trans? I am not sure if anything even connects to the man trans...

It would be cheaper that way too. Otherwise, the wreckers would charge a quite a bit for the whole harness....

Your best bet is probably going to be a you pull it yard, and since your town is close to Indy, you shouldn't have too much of a problem finding one.

I just bought a this car and got it home and started having various electrical/wiring problems. Apparently someone removed engine/trans without properly disconnecting everything. Pretty much everything was cut, then but-spliced later. I have had to re-run wires from the ecm to make stuff work but I am still dealing with a lot of intermittant stuff. I may be interested in an ECM +ecm mounts too, I am sure this wiring mess hasn't treated it nicely.
