I am still trying to fix my running lights/tail lights. I was wondering if the 'lighting relay' plug in the fuse box under the hood can affect the tail lights? There are only two relays there: The 'dimmer relay' (5 pin plug) and the 'lighting relay' (4 pin plug). Since there doesn't seem to be any way to tell if it is wrecked or not, can anyone tell me what it controls? If this step doesn't work I am going to try to replace the Driver's Multiplex control the unit (is this on the steering column?) or the headlight switch it self.

Thanks for answers to any of that,
Will.
