I've looked everywhere for the door lock relay and can't find it. I know where it is on my 85, but I'm working on a 90 and it isn't in the same place. Does anyone know where it is?

Here is the problem I'm working on. The door locks and power seat don't work. The Pwr Accy relay cycles constantly and had to be removed. A check of the current across that junction reveals a draw of 100 amps (nearly burned up my meter).

So I know I have a direct short, but after removing nearly the entire front interior to check the wiring, the only thing I've been able to isolate is that there is a connector under the center console that has one black and one orange wire coming in, the mating connector has one black wire (mates to the orange wire, shows shorted to ground) and one black wire w/blue stripe (mates to the black wire). The short can be seen by checking the orange wire at either door lock switch connector to ground. If I separate the connector under the center console, I can no longer detect the short at the door lock switches on the orange power wire. But I can still see the short on this mating black wire.

Anyone know of any component failure that can cause a short like this? Or does anyone know of any other connection point that will allow me to further isolate the location? All the wires lead back to the main bundle and I can't seem to trace them to the point they come together.
