I recently put a new Pioneer stereo in the wifes 87 tdt wagon. I used only the (batt) + wire, the ign + wire and ground from the stock radio harness, all others were insulated and stowed. About 1 day after the install my wife stated that the dash lighs went out while she was driving, and yesterday I put in new bulbs in the fog lights because one was out. Now they do not work either. I checked the fuses under the hood, drivers side fender well. All were good. Some of the fuses were the older aluminum type so I bought all new BUSS glass envelope replacements, and swapped out all fuses. I have the MB 124 chassis "Bible" and looked through it for any hints, but no luck. I also have the repair manual on cd rom and did not find anything in there. so here I am.

Saying that your help is appreciated would be an understatement.
Thanks a bunch.

Did you figure this out yet? I'm positive that there is a loop in the radio for the lights but I don't have a diagram to see this for sure. Same thing happened on the in-law's '89 300CE but I've not diagnosed it yet.
