I'm having difficulty determining what type locks a 92 grand marquis has. If someone could let me know what type it would be appreciated.

Does it have the keyless entry keypad on the outside of the driver's door?

Does your vehicle have keyless entry? If it does then they should be straight negative trigger. If it doesn't, then they are reverse polarity, and look in the relay section of this website to get a diagram on how to wire them properly. the wires should be located in the DKP and should be lock ------pink / YELLOW unlock --------pink/light green ------------- ...half of the truth can be worse than a lie. <----Roger Russell said that..

the power window /doorlock panel only has one clip in it snap it out and look one that has factory keyless will only have 3 wires at the switch

At the switch there is the pk/grn, pk/yl, and blk/wht 12v.

The diagram below seems contradictory to what's been stated here. The diagram was taken from the Vehicle Wiring section here. | Door Lock | Pink / YELLOW | Behind Glove Compartment w/Keyless w/o Keyless (-) | | Door Unlock | Pink/Light Green | Keyless Reverse Polarity |
- robertsc states, "one that has factory keyless will only have 3 wires at the switch" and joch1314 suggests, with keyless entry, this vehicle has 3-wire negative door locks system. The diagram states "Keyless Reverse Polarity".
- mcscory05 states, "there is no factory keyless entry" and finds a 3-wire positive(blk/wht 12v) door lock system.
It all seems confusing to me. ------------- Ideal - cmon dude, add to topics in a useful manner, not stuff that is obvious.

If it has no factory keyless, then it's definitely what we either call "5-wire" or "reversing polarity."
You'll need two relays, and you can follow the diagram on this site, or the one that should come with whatever you're installing.
Some people like to get the wires above the glove box, but I was never able to find them.
I just unfasten the rubber boot that's between the driver's door and the car body, temporarily shove the boot into the door cavity......bring my aftermarket wires out there into the door jamb, make my connections, and put the boot back on.
The only thing there is that because the wires get flexed a lot, you have to be extra careful to make good connections.
When following the diagram, and you're inside the door boot, and you cut the wire in half, the "door" side is equivalent to the "switch" side......and the "body" side is the "motor" side.

that's where another source said to find them but no luck behind the glove box. i tried wiring according to the 5 wire diagram and blew a handful of fuses but i wired in the relays right behind the switch. So i need to catch it after the driver door ? i appreciate all the help. i

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

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.

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!!

You can use the BLACK/ WHITE at the switch, as well. ------------- Ideal - cmon dude, add to topics in a useful manner, not stuff that is obvious.

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

it sounds like its a 5 wire a three wire wouldn't blow the fuse go pay somebody to do before you damage something

I wonder if we'll ever hear the resolution.
