I pulled this free alarm off an 85' c10. It's older about 1999... Anyways, I'm trying to figure out how to wire the dome light outlet and door switches (-) & (+). I just finished the keyless locks but I got to this and it stumped me. Because it seems the switches are the (-)?????? Idk though can someone help..? Here is the link to instructions... http://www.blackwidowsecurity.com/in...%20Install.pdf

Page 12 is my diagram

Also.. When it says for instance "Lock/Unlock polarity" is this wire supposed to be a ground?? Or what?

 

Yes, dome light switches close circuit to ground, hot is constant.

 

I didn't see this diagram until after I wired so my door locks aren't working keyless

Do we have positive pulse door lock systems, negative pulse door lock systems, or do we have reverse polarity factory door lock system?

Got alarm working, just this one damn thing and is our door locks negative door or positive? How do you find this
