The input is directly from the switch, it is on a 92 an orange/vio(orange with purple tracer. Any open in this wire will disable all locks. Lock output wire is orange/white. At body comp. Both The only other way would be to use a real good scanner to see if their is a "disable" function. The DRBIII in any Chrysler shop may or may not. A circuit breaker and a 20 amp fuse protects all circuits. Taking either one out will disable. Why not see if maybe it is possible that the lock relay is closed all the time and maybe this is what is wrong, it is mounted on the left side of dash, the unlock relay is on the right side. Swap em.
These are the only options I see. I'm glad to help you.
