I am attempting to install a Valet 712T in my 97 GMC truck, two door. From what i can find it has 5 wire reverse polarity wiring. The installation manual is very vague about whether i need to add relays or not, If someone can help me out on this it would be apreciated. Hopefully there is enough info here to get an answer if not i will try to add what is needed. Thanks in advance

can you specify which gmc truck exactly? Also you can't have five wire reverse polarity, it's either four wire reversal, or five wire alternating, again u need to specify!

You dont need to add relays, they're built in. Follow the diagram for the 5 wire, reverse polarity diagram in the book. That old 712T is a good unit.

Ok the book isnt the best for someone that hasnt done this before, i have wired in lights , radios and sirens but never one of these so i will type out what i think i should do and see if this should be right. Of course i know where the red and black wires go and i have the parking light flash wire working. So i think this is how the wiring should go for the door locks. I am adding the color of the wires for the door locks according to what i found on the color of wires for my model of truck. GREEN/ Black from the unit would go to the Light Blue on my truck for lock Blue/Black from the unit would go to the White on my truck for Unlock The Violet and Violet/Black run into a fuse block down to one wire it take it that goes to a 12 v the BROWN / Black and WHITE/ Black im not sure where those would go. and do i need the Yellow wire hooked into the ignition, this unit at one time was in a crown vic and the yellow wire wasnt used there. Hope this is understandable

GREEN/ Black from the unit would go to the Light Blue on my truck for lock

the BROWN / Black and WHITE/ Black im not sure where those would go.

ok, you need to cut your factory lock wires ( white and lt. blue) the BROWN / black and the WHITE/ black need to go to the switch side of the wires and the blue/black and the GREEN/ black need to go to the lock motor side ( the side that should go into the door).
i think the WHITE/ black wire goes with the GREEN/ black. the the BROWN / black goes with the blue/black. i'm really not sure, it could go the opposite way so be sure to have some extra fuses on hand.
purple goes to 12v constant
but first, are you using a 451M lock module? and are you sure you are dealing with a real 5-wire lock system and not just positive locks? you can check this with a meter and verify if you have a 5-wire locking system if both the lock/unlock wires rest at ground and one wire will be positive when you press the lock/unlock switch. if they do not rest at ground then you have a positive lock system most likely. -------------

Ok this is what i have according to commando car alarms
POWER LOCK LIGHT BLUE (5 Wire Reverse Polarity) See NOTE *2 IN EITHER DOOR BOOT
POWER UNLOCK WHITE (5 Wire Reverse Polarity) See NOTE *2 IN EITHER DOOR BOOT
DOOR TRIGGER PURPLE (-) @ HEAD LIGHT SWITCH
I copied that from their web site. And no i do not have a 451M. Is that something i will need

no, you dont need the 451m but you will need to get 2 spdt relays and wire them like this and make sure you put a 10 amp fuse on the constant 12v wire to the relays. -------------

does it have a plug on it that has a purple, a blue/black, a GREEN/ black, a BROWN / black and a WHITE/ black. or does it just have the 2-pin( or 3-pin) plug with a green and a blue coming from it.
if it has the plug with the 5 wires then you wont need any relays, but if you just have the small plug with just the blue and the green then you will need to use external relays and wire them like the diagram. -------------

It has two purple going into a fuse and it has blue/black, GREEN/ black
BROWN / black and white black.along with mutiple other wires that i wont use except for the parking light flash and horn honk. the whole plug has a total of 18 wires coming out of it

ok you wont need any relays. do you have the install maunal? it should show you how to wire it up to work your 5-wire lock system.

yeah i have it, but not sure about the purple wire , i take it that it needs 12 volts constant

yes the violet/black and violet which are common at the fuse holder require a twelve volts source which is at least capable of supplying 15 amps of current. ------------- COMMIT YOUR WAY TO JEHOVAH AND HE WILL ACT IN YOUR BEHALF.
