any kind of help would be great

The 712 has built in relays for locks.

5- GREEN/ blk Lock #30 Common output

  6- wh/blk Lock #87 Normally closed  7- Violet/blk Lock #87 Normally open (input)  8- Blue/blk Unlock #30 Common (output)  9- Violet Unlock #87 Normally open (input)

If you understand the relay, using the pin#'s wire it for negative pulse. Both of the 87 will go to ground, the 87a you will NOT use. the 30 will go to the wires in your car.
