Hi, I have a 89 mustang gt I'm trying to wire up the viper 3105 alarm to lock and unlock with the remote. Ive read a few sites talking about the 5 wire relays, but it's not working. When I wire it up as soon as I attach the 12 volt positive the locks lock. Can anybody tell me how to wire this up correct? ive tried this way so far. @2spdt relays. 87,86 on one, 85 on the other 12 volts positive. on the lock relay 30 to the lock 87A to the switch and 85 to the wire from the alarm. the the unlock is the same except 86 goes to the alarm. This is how I wired it and it was called 5 wire 12 volt power door lock. does anybody have a way that actually works. Thank u.
