Power Door Lock Question

Hi all,

I just bought a set of aftermarket PDL for my ford ranger and was looking over the installation instructions, what there was of them...It came with two actuators, 5 wires each (Blue, Green, Brown, white, and Black) and a central locking control module.

What I want to do is interface the PDL in with my alarm system so they open and lock with the key remotes. Its my understanding that the alarm is capable of drivers door priority using a second output from the alarm module.

My question is should I throw away the control module that came with the PDL and use the three relay setup and cut the brown, black, and white wires at the actuators. From what I can see they just provide a ground pulse to the PDL module indicating if the actuators have been manually locked or unlock to operate the other actuator.

On the relays I was going to wire them as follows:
relay 1:
86 neg lock pulse from alarm.
85 12 V+
87 12 V+
87a ground
30 green lock wire to both actuators.
Spike Diode between term 86 & 85.

relay 2:
86 neg unlock pulse from alarm.
85 12 V+
87 12 V+
87a ground.
30 blue unlock wire to drivers door actuator only.
Spike Diode between term 86 & 85.

relay 3:
86 neg secondary unlock pulse from alarm.
85 12 V+
87 12 V+
87a not used.
30 blue unlock wire to passengers door actuator only.
Spike Diode between term 86 & 85.

Note: install a blocking diode between passengers actuator blue wire and drivers just before relay 2 term. 30 so it can still provide ground during locking so both actuators will lock with lock pulse.

Wish I could post a pic, but I dont have a scanner. Sorry.

Thanks,

Rev

Cut the brown, black and white wires near the actuators, as you suggested. But you can still use the control module that came with them. The white and brown wires on the module will be the trigger wires that you will connect to you alarm. I had power locks like that i purchased from JC whitney years back. They would act up sometimes untill I cut the brown and white wires, now it works fine. But if you really want the drivers door priority, then your relay setup you described would work fine.
