If your diagnosis is correct, it sounds like a 3-wire positive door lock system to me, regardless of what the diagram says or has been stated here.

Tap the PINK/LIGHT GREEN or PINK / YELLOW at the switch, through a 1-amp in-line fuse, across a 12v source. The doors should unlock or lock, respectively.

Ideal - cmon dude, add to topics in a useful manner, not stuff that is obvious.

Story - Phzzzt! Hey, what happened?! ... Isn't it obvious?

Moral - Never dismiss the obvious.

I always say...better to blow fuses, than hook it up without them and not have any fuses to blow. You'll become an expert with five wires when you're done with this!!

...half of the truth can be worse than a lie. <----Roger Russell said that..

You can use the BLACK/ WHITE at the switch, as well.

wires at the switch will work fine

the reason you were blow the fuses

you probably had the wires at the relays reversed

you need to determine which side of the wire is motor or master switch to determine

which way to wire your relay

I tried reversing pin 87a and 30 and it's still blowing the fuse.

I'm not understanding. As it is now, i have the 12v blk/wht with a 30 amp inline fuse. When you touch either pk/grn or pk / YELLOW the fuse blows. I apologize. This is my first alarm installation. The Presitige manual is very unclear and offers help on only one type door lock and the website offers nothing. I should have made my screen name "The diy dumb@ss" lol

Yes. I also tried swapping pins 30 and 87a to see if it was the wrong side

The fuse will naturally blow if you apply the 12V directly to the pink / YELLOW or pink/green, since the wires rest at ground when the switch is not being pressed.

Testing with the relays installed could be done by grounding the control terminal of each relay (i.e. the terminal that's connected to the (-) output from the keyless entry/alarm/RS.)

He stated there is only 3 wires at the switch. How could it be a 5-wire reversing polarity?

it sounds like its a 5 wire

a three wire wouldn't blow the fuse

go pay somebody to do before you damage something
