What's the best place for you RS to hook up to on a 2002 GMC Serria. The alarm is a autopage 850lcd. Having problems tracking down the tach wire.

go to any coil pack under hood and there are 4 wires 3 of them are the same on all of the packs the odd color is your tach use any of themand youll be ok

Well I found a tach wire and it's ok but not the truck turns over and dies. I have a DEI 555L and it's wired up right I think. Anything on my autopage alarm that would cause it not to fully crank over??????

Thanks

put a key in the ign. and try to start it again....if it stays running, then you dont have the bypass working right.

on the 555l make sure that the passlock ground is hooked up in the right place.
