OK, I pulled the dash out of a 91 Dakota to hijack the wiring harness. Over in the right upper kick panel is a black box about 5" square with a wire attachment of about 10 wires (I didn't count them). I know the mid 80s cars had a logic module in that kick panel, but I thought those went away with the OBD1 system. Is this box the equivalent to the logic module? My coupe has a dash wiring harness from a 90 Dakota in it and I don't remember there being such a box attached to that harness, but that was 5 years ago.

The OBD1 ECU was under the hood and the truck was a stripped down v6 5 speed with very few options. This box was pretty well hidden behind the heater/ac unit and I didn't even know it was there until I pulled the dash.

What am I seeing? Of course I don't have a picture of the box, but I suppose I can get one. Gene
