I posted this in the electronic forum but didn't realize there hasn't been any activity since January.

I need some help with the door locks in particular on a 1990 Q that I am attempting to wire in a Viper 4105 keyless entry/remote start. For now I just want to get the keyless entry working. It had a CodeAlarm keyless entry system that was installed back in 1997 by the previous owners. I am trying to figure out the door locks. I noticed that after I put power and ground to the unit that when I push the lock or unlock button on the remote, I measure 1.5 volts at the output wires for the door locks. I thought they were suppose to read as ground according to the Viper diagram. I'm hoping someone on here has wired up a similar system and could tell me how the door locks were wired. I'm not concerned about the horn or parking light flash option right now.

Again the unit is a Viper 4105V unit.

Thanks

Try the jumper on the alarm...it should pulse negative... try the other door wire...1994 Q45part 791xv remote start....
