I was cleaning up my RX-7 today and starting to look over what else I'll need before I can put the engine back in and noticed some damage to my main harness but I'm not sure of the amount of harm this will have. My car started life as an automatic and I swapped it to manual but I retained all of the automatic wiring and just added what was needed for manual functionality -- thus the harness is untouched except for the main PRNDL connector where the starter-interlock resides.

Here are some pics of the damage.


The entire main harness from injector wiring to transmission pigtail.


The large gray connector in the middle is the PRNDL connector.


A little closer, you can see where the tranmission pigtail harness juts off on the left of the image.


Further down the harness, the PRNDL conn. close up.


Further down the pigtail, leading to the speedo sensor wire and mysterious connector.


The messed up connector.


Close-up of the connector in question... ignore the two stray leads... the connector for the speedo sensor was also broken free during the engine removal.

Thanks,

I dont know what that connector is, is it related to the automatic? My recommendation is get a new harness if that one is old and crusty. I 100% believe that not replacing my harness is what caused my last motor to go lean and pop on the dyno with only 500 miles (killed a rotor, plate, and housing). Another rebuild and new harness with nothing done to the fuel map and I am pig rich, down below 9 afr when boosting. Whatever was making me lean on the dyno is gone and harness is the only thing that really changed.

Well, my harness really isn't in that bad of shape outside of the one connector I seemed to destroy and the speedo sensor I bumped (common problem and I should have been more careful as per the FSM guides) The car only has 68,001mi on it thus far and within the first month of buying it (58,023 IIRC) I had bought and installed a downpipe, Koyo radiator, Pettit AST and silicone vacuum lines. Reliability mods FTW (risky mods like midpipe, FTL)

As for the connector's location, it appears to be on the same pigtail as the rest of the transmission connectors but it has been a good while since I did the auto-to-manual swap and I performed the wiring in an unconventional way as most swap the harness as well. I should still have a backup of the FSM on my old HDD, I'm going to try and find it tonight and see if it lists that connector anywhere.
