The FB05 has a dimmer delay circuit for the key lights in the doors and at the ignition switch.

Other than that, the FB01 is the same.

ANY IDEAS? thanks guys
Exactly what is not working? The running lights are not related to the CPU, only the turn signals, but either way should not be switching on with the key.

But it gets back to what exactly is not working?
