2002 ram 3500 ctd 6 speed 4x4 with 4 wheel abs had a interior fire replaced all the wiring from an 01 including some exterior wiring..using 01 comp on firewall and 02 comp on the engine..would this throw the lights? the light comes on and off at random points and the speedometer works at all speeds...also the 01 was a 5 speed would that effect anything?the engine seems to run strong and no CEL...taillights also work so does 4x4 light..thanks for the help..
