Rear Defrost wiring info?

[hollifm]

I am trying to hook up a aftermarket remote start. One of its options is to connect to my rear defroster. I can see the wires up in the dash but is there a easy connection near my fuse box? I am unable to find a wiring diagram for the rear defroster (colors, etc.).

Any help would be appreciated.

Thanks,

hollifm

If (simplest) you can splice into the blue/red wire from the defogger switch, defogger is on when this wire is grounded. Otherwise (harder) follow this wire to pin 11 of 22 pin connector B-66 on the J/B (note: the inside fusebox is on J/B) and also to pin 6 of 20 pin connector B-47 of the ETACS-ECU (which is on the back of J/B - can be seen behind cover if open drivers door). PM me if need further info. I own a 99 GST also.
