I have a 97 Jeep Cherokee that i am installing a starter/alarm in. The alarm is a Delta Pro 5005. I got a printout of the wiring from my buddy at Best Buy and it says I must use relays to trigger the door locks. The Jeep has factory door locks on it, they are 3 wire negative. The alarm has 3 wires for door locks,

[green] lock output (-)500mA
[blue] unlock output (-)500mA
[red] +12V relay trigger output 100mA

Well my question is how would i hook this up and if a relay is needed, what one(model # or whatever), where would i get it and price estimate, and how would i go about hooking it up.

It's on this site under diagrams. Heres's a quick link to the page. Just use the 3 Wire Positive Door Locks
but change both normally open terminals (87) from 12V(+) to ground as it shows.

Power Lock PINK/VIOLET EITHER KICK #201
Power Unlock ORANGE / VIOLET PANEL

#201- See Negative Pulse Door Lock Diagram.

if your door lock outputs are neg. and the car has neg, have you tried to hook them up direct??

i havent tried that yet because from what i was told, the factory door locks are high current so i would need a relay.
