Wiring up alarm door locks

[dwenrhod]

Hey guys, a couple years ago I had a Viper 3002 alarm system installed in my truck. At the time, I had shaved handles so the door lock part of the alarm was never installed. I have since gone back to having door handles and would like to wire these up. I was looking at the manual and it seems pretty straightforward but I have to pick one of a few different door lock circuits. Any idea which one it is? It's a 1993 C1500 RCSB silverado trim

Type A - Three wire (+) volt pulse controlling factory lock relays
Type B - Three wire (-) ground pulse controlling factory lock relays
Type C - Directly wired (no factory relays) reversing-polarity switches

I took off the panel for the switch and there are 5 wires on the switch in an h shape. It's obviously not the first two types right?

Thanks

TYPE C these are 5wire locks - no OEM relays.

if you are using relays do this:

87 - +12V
87a - switch side of circuit (will show 12V when cut and switch pressed)
30 - motor side
86 - +12v
85 - trigger input.

you will need two relays.

grab lt blu and dk blue in teh drivers kick panel and test them. one will be lock and the other will be unlock.

that should point you in the right direction
