compustar 2wssr cm3000a, 95 caprice

Correction, vehicle door switch lock/unlock relay wires are white and blue. should hold true for all gm B/D body caprice, impala, roadmaster, cadillac and maybe trucks.

Oh yeah, i'll fess up. with a set of aligator clips i test hooked the + door lock/unlock wires to the (-)lock/unlock blue/black &blue wires form the brain. Did i f it up ?

You will need relays to reverse the polarity of the (-) trigger of the Compustar in order for the door locks to work at all. Using a (-) trigger will do nothing to the door triggers.

just got back from radioshag toting a bunch of t-taps and a couple diff relays. they only had mini spdt relays (275-248) but they had the standard automotive spst relays (275-226). I believe theyre the potter blumfield cause they are made in the UK. Anywho, although the faqs have a diagram for spdt switching, but I believe an spst is exactly what I need for this application. It doesnt have the 87a term, but it has 4 lugs - 2 for coil at 160mA and the 30A 12V relay switch. I was looking at the inline fuses in the shaq, guess I shoulda bought a couple. I suppose the +12 to the lock solenoid should be fused at least 10A ? I hope I didnt kill the brain w the + I sent to the (-)250mA trigger wires.
