Did heater core, now have no ATC response, an air bag light, and a non fuctional gauge cluster,Map lights dome lights. Need Wire Diagrams!!! Have a chilton but its useless. NEED HELP QUICK!!!

 

Sorry Guys, Car is a '94 Concorde 3.3 with ATC. I also have a mystery plug that has eight pins. The pinsappear circular. and are on a bracket that has two holes that appear to be for mounting the plug. Cant see an obvious place that it goes.

Here are the colors of the wires in the plug from one end to the other
1)BRN 2)GRN/(looks like a tan)3)PNK 4)RD 5)BLU/WHT 6)LT.BLU/BLK 7)GREY/BLK 8)PNK/BLK. Any questions ask me, thanks guys

 

u are asking way to much for that kinda issue use shop key or mitchell on demand if u have it in your shop. U are asking for 20 pages atleast look for a common thing that u did pinched a harness or something.

 

ok, map lights and dome lights are ok, I need a diagram of what controls the cluster, it powers on but no signal, tach,speedo,fuel, temp....nuthin ill post a pic of the mystery plug today.

 

sorry like i said b4 to old to get a wiring diagram from the dealer we dont have books that go back that far and if we did they are torn and crap from hell. get shop key or mitchel on demand

 

Ok, the odd plug was the message center. so now there aren't any more connectors without a home. I called Chilton tech assist. and they e-mailed me a diagram for the cluster and how to pull codes out of the ATC. The ATC isnt giving me any codes and the LED's to say what mode you are in isn't illuminating. And the diagram was "cluster specific" so i dont really know what gives the cluster it's data. Is it the BCM? Could the BCM also screw with my ATC if its faulty? I need a "data flow list" so to speak. I pulled out the dash again and didnt see any pinched wires ect. I just need to know some possible causes of losing all the gauges. the ground is good.Also the car always read around 400rpm's with koeo. And it still does. so it appears to be getting power. BTW I no longer have access to alldata,shop key, ect.

 

ok, found parts car, tried new BCM ATC and cluster, some thing ARRRGGGG
