Viper and door lock switches

I have a Viper 3100V alarms with door locks. I also have put in power windows and mirrors. I have the controls for door locks on my panel. Is there any way to hook up the switches to the actuators so that I can also use my door lock switches. I have a 97 Ranger XLT. I saw a posting the says take the wires from the viper to the actuator to the switch and then black to ground. If that is the case do I put it in fron the actualtor and then take those same wires to the actuator?

No, its a little more involved than that

Door actuators work by momentarily sending the actuator 12v/gnd, or grd/12v on its 2 wires, so reverse polarity to either lock or unlock

The door switches are made to activate relays, not the actual actuators, so low current switches
The switch controls the ground on the two relays, unlock relay and lock relay, so that part is correct
Both relays GROUND both actuator wires when off, so you actually want to send 12volt to an actuator, but that would cause a short to ground in the Viper unit

When you press the unlock button direction it grounds the unlock relay which activates it and sends 12volts to actuator on 1 wire, the other wire is already grounded, so actuator moves
Same happens with Lock button except the Lock relay activates and the other wire is 12volts

If you have access to the Viper relays you might be able to do that

You could add 2 relays inside each door, but it would only be for that 1 door, unless you ran 2 wires between the 2 doors, so each switch could activate both doors

This is an example of factory door lock setup wiring

The RAP module(remote persionality module) was the Ford key FOB entry unit, just FYI

Thanks for your response!

So I do have access to the relays for both doors because the way the viper works is it has two wires that come off the control unit. a lock and a unlock wire. They split onto each relays that I had to add for the actuators. So I guess I would do the same thing in that I would take the two wires that come of the switch and hook them into the same place the two wires that come off the viper control unit that go into the relay and then hook the switch ground to ground. Here is a link to the viper installation manual.

Viper shows both + and - triggers

So you have one Lock relay, and one unLock relay, and both doors lock or unlock at the same time

You installed the relays then you should know if they 5 pin relays and if they are activated by grounding, which is how the door switches work
