I am installing an alarm in my 1999 Dodge Dakota R/T with factory power locks, we cannot figure out how the locks work in this thing. When the alarm send a + pulse to the unlock wire it unlocks then immediatly relocks again, and it does the same thing on the lock wire. I know it isnt the alarm cuz it does the same thing when you just tag either wire to positive. It says in the vehicle info LOCK= ORANGE / Purple REV and UNLOCK= Pink/Purple (+) I am assuming that REV is reverse polarity, but what exactly does that mean?!?!

The way my alarm works is simple, when you press unlock it sends a (+) pulse through the unlock wire and when lock it sends a (+) pulse through the lock wire, so what do I need to do to make this work??

What kind of alarm is this ? Not too many systems that I know have a (+) output door lock control as it's primary output. Most of the time it's a (-) trigger or at best a alternating polarity system. Here's the what you need to do to make ths system work ( keep in mind though that this is for a (-) trigger based system )

5 wire door unlock you have to use this diagram: https://www.velocitymotorsport.com/images/install_notes/C.jpg

The LOCK uses a (+) system that you will most likely need a relay for to trigger on most Dodge vehicles to ensure proper voltage goes to the motor wire.

It is a Royal guard and it does use a positive pulse, you can configure it for both positive and negative pulse.

Circled is the digram i was using.

I am confused as to why the unlock on my truck is + and the lock is REV?? What does that mean exactly?

I do think I understand the diagram you showed I see that it opens the original curcuit that the switch when the alarm send the lock or unlock pulse, is that what is conflicting?

Well I wired it up again like in the diagram and all is working fine, except I think the unti was damaged in our previous tried because it no longer sends a "LOCK" pulse posted_image

Only the Unlock feature works. D^nmitt!!

I just did that thing a couple days ago. The lock is a strait positive pulse and the unlock has to be 5 wired. If you did not do that when you hooked it up originally its quite possible you fried the output on the brain. Sorry dude, wish I could help more.

The thing i dont understand is...all the output on the brain is, is a relay and it is a NO connection, so if something backfed into it, it would stop when it got to the relay it would have nowhere to go, and even if the relay was engaged it would only connect to the common which i had fused (if you look at the diagram above youll see what i mean) Nothin should affect the coil of the internal relay because nothing connects to it so how did it fry??

you burned a trace on the board of the alarm that controls the lock function.
