1996 Chevy Truck Keyless Ent. Prob

I just installed an UltraStarter 1250 LR-AM remote starter keyless entry system on my truck.  The truck is a 1996 Chevrolet full-size extended cab. Everything works fine except for the keyless entry.  The locks on my truck require a positive pulse to operate and the brain for my remote starter provides a negative pulse. So i wired up two relays to make it work, just as the wiring diagram in the owners manual said to do.  When i first tried the locks they worked, and then the lock function quit working and the unlock function was the only thing that would work.  After that the unlock function quit working as well.  The wiring for the relays works fine. If you take the lock harness out of the brain and ground either one of the wires the locks will unlock and lock so i know my wiring is right. ANY help with this problem would be greatly appreciated.

Thanks

Also, While hooking up the Remote start wires for my truck, ignition 2 is supposed to be a white wire, but i could not find a white wire in the ingition harness that was a 12 guage wire, but i did find a Pink with white wire that was not powered with the ingnition switch off but had power with it on, and i read somwhere that it was possible to have a pink with white wire instead of the white wire that was listed on the printout. Is this correct? I have no check engine light and everything works fine. Any help greatly appreciated
