Alright, I have 2 wires coming from my alarm that constantly show 12v+, these are my lock and unlock.  Now I am trying to plug them into the factory alarm harness but heres the problem.  The lock/unlock wires require only a pulse of 12v+ to lock not constant.  I've tried almost everything with relays but I'm still stuck.  PLEASE HELP, I've been stuck for almost 2 days.

I think you are reading the pull up.

when  you press a button, lock for example, the lock wire goes ground ?

if so, add relays to make the pulses positve.
