I installed a set of power locks in a jeep wrangler. The kit was from parts express and came with 1 5wire actuator and 3 2 wire ones. It came with the necessary wiring including the relay needed for the locks. The locks seem to work fine when i lock the driver door it locks the passenger door, same with unlock. My problem comes in whjen I interface it with an ungo 8300 alarm that is installed in the vehicle. It is set for (-) output and the unlock and lock wires are hooked to the correct wires of the kit. When arming the alram the locks lock perfectly however sometimes on UNLOCK the locks unlock then quickly lock back?? Same with opening it with the key and pushing the lever inside the car. If you unlock and hold it for a sec it does not automatically lock back. It does not do this every time?? I have tried changing to 4sec duration on the pulse and also double pulse. What do you think is causing this is it the alarm resending a lock signal or is it in the wiring/relay somewhere?? My next idea is to just unhook the lock wire from the alarm to see if it stops the problem. If it does then I guess it is in the alarm somewhere but where do I go from there?? Any help or ideas would be appreciated. Thx

Sounds like the lock wire is grounding out somewhere . Check to make sure that the lock wire is not pinched or cut between the actuator & the Ungo system.

hey, do the doors come off of your jeep wrangler?
Just curious...because if you installed actuators
and had to run wires to the door, how can you take
off the doors now?

I got it dude. Your problem is the 5 wire Actuator when you install it make sure that is installed in a way that doesn't see a lot of resistance. Meanning that is very hard to move lock and unlock switch by hand. What you can do is to make sure the switch can be move as smooth as possible. What is happening now is that when you unlock, the motor bounces a little bit back just enough and triggers the lock circuit relays to relock. The 5 wire motor serves as a locking switch, whenever you move the lever it triggers the relays. But to solve the problem wire it as 2 wire or install a 2 wire motor. good luck ( if you install a 2 wire motor the locks will operate from alarm, make sure you activate ignition control locks. P.S. Jeep Wrangler locks??? that a first. ------------- Luis

Is up to the installer to test all wires with a DMM whenever possible.

You guys are probably right, I think I will change the way it is wired anyway i really just need the locks to unlock with the alarmn anyway. I have some extra actuators from the kit as it only has 2 doors and one wont fit for the tailgate door. can I just unhook the 3 other wires that go to it or does it depend on how the relay in the one that came with the kit is wired? It hasnt done it at all today so ill prolly wait til the weekend...thx for the help

I wired each door wher the looming comes out from behind the door panel then up under the dash. When the door is closed it curves along with the door strap..I wired a connector in line on each side so when the doors come off you just unplug and go...
