Wiring up alarm door locks

[SinisterSilverado]

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
