I've installed the Autopage 750LCD alarm and everything works except the remote start. I've also got the DEI 555L bypass module. However, when I go to remote start the car it will try to start but die immediately. I've tried both voltage and tach settings and neither will work. The only wire on the 555L that could possibly be wrong is the blue/black, and I've got that hooked to the pink wire of the 750 which is programmed to send a 1 second - signal which is what the blue/black is supposed to look for. Help! I don't know what else to check or look for.

Thanks!

it sounds like the pass II system is not by-passed yet.

sounds like you may be using the wrong output from the rs750, try using the ignition 3 control output (it may be the yellow wire as it stays active until you hit the brake pedal, but the wire you are using only stays active for 1 second, and the passlock II shuts down the vehicle after that one second

As stated above, you need a wire that stays (-) throughout the whole remote start process, not just a 1 sec pulse.
