Add On Remote Start

I've installed the unit in the car. It has a pink activation wire that requires ground. I can touch the pink wire to ground and it cranks and runs fine. Works perfectly that way. I used the wire that shows 12v when the lock button is pressed on the keyless remote. I reversed the polarity with a relay to send ground to the pink wire. This does not work, ever. I don't get it. I test the pink wire and it's getting ground at the brain when i press the lock button, but it won't activate the remote start. I've tried 4 different relays and even tried getting a better ground but nothing works. This is the last add on I try to do. Let me know what you think.
Thanks

soundzgood: "I used the wire that shows 12v when the lock button is pressed on the keyless remote."

you must have the relay hooked up wrong.
85-ground
86-your (+)12volt input (am assume that this is the lock wire that you provided)
30and 87 ground
87a-none

doe it have factory ignition kill upon hitting the lock button?

sorry about that 30 and 87 are ground and initiate input(-)
