Default Jb4 broken connector pins - 09-19-2020, 03:03 PM

So my friend was having trouble with his jb4 throwing his car into limp mode so he gave it to me and after very little investigation 2 pins are missing and 1 is broken on the main connector into the jb4 system itself. Is there anyways i could fix those pins to run it in my car?

there are many unused jumper wires in the jb4 harnesses. The jb4 jumpers have a wire/pin for every dme slot even if the dme slot is empty/not in use. look for an empty dme slot and move the jumper wire. otherwise a new harness set is expensive.
