csnow, thanks for the direction to the past posts on the seatbelt warning relay. I tried to get the pics to come up, but those sites are no longer supported, so I have an email into Aaron (300speedyDturbo).
As for the rear light, I have replaced the bulb and the switch on the dask console. No luck. I don't think there is power going back to the unit.
You had mentioned to test the door switch with a voltmeter...what will a good operating switch read? I'm guessing 12v, but I am electrically challenged.
