I took a quick look at Davey’s for a picture of the replacement OBDII plugs and one of the pictures used appears to be wired like my Jeep. That is weird.
My plan is to move the two terminals that are out of place and see if my friends scanner will access the PCM and go from there possibly taking it back to the dealership to check access with the DRBIII.
I am not that familiar with further testing the wires myself. Looking at some of the diagrams some of the wires branch off to other modules. I don’t want to short those modules by incorrectly testing the wires. i might try the PCM if the terminal relocation on the OBD port does not work. Then replace the repaired dash harness if the PCM doesn’t work. Both are about the same price and substantial differences in labor.
It would be nice to have wiring that I know is good and not adding resistance or repaired incorrectly. Used dash harnesses are a few hundred dollars. I am not looking forward too the labor involved with replacing the dash harness.
Side note. Is there an aftermarket scanner I can buy that has full or most of the functionality of the DRBIII?
Any recommendations welcome.
Dealership is $250/hour. Trying to stay away from there.
