Hey integra87, did you ever find out which one is which?
I know the 2 black wires on the original are heater wires, and if they are crossed, it doesn't matter.

I thinking the gray wire is signal and the black is ground?


I might be wrong...damn..

I hate to bring up an old thread but I cant seem to find nething like this in the search. I searched google and this is the first that comes up... I know its old, but I have this same problem. The universal is HALF the price of the plug in. I cant justify that... is the above posters wiring assumptions correct?
