1995 dodge ram door locks

[yerav]

I have a 95 dodge ram with factory power door locks. I installed a remote starter with remote door locks an d the remote wires are a neg. system and I need help in hooking up the wires. Do I need relays and if so how do I wire them in Thanks Yerav

Those trucks are either positive locks, or reverse polarity, usually reverse polarity. either way you will need to add relays, disinguishing between the two systems can be difficult, because both will appear to be positve when using a test light. for reverse polarity you have to cut the vehicle lock wires and send power down the motor side but not the switch side, if you mess this up you WILL cause a fire, because the switch side rests at ground.

Good luck.
