Hello,

My dilemma is: I have a 1995 Chevy Gladiator G-20 conversion van I have installed an alarm system and have everything figured out, installed, and working accept the door pin switch that sets the alarm off and the door lock-unlock wire combo.

The door pin switch is a negative switch I believe which the drivers door pin switch has 2 wires connected to it and all the other ones (passenger, side, and rear) only have one wire connected to them.

The factory door switches have a 3 wire connection. 1st constant hot(orange and black), 2nd one negative (solid black), and 3rd negative (blue) wire.

Looking at the manual from the alarm is where I am getting confused. It’s showing at the top of the box unit a small jack that has three wires saying blue-unlock, red-12v + out, and green-lock. Then looking at the side of the alarm control box there are green….(-) door trigger, blue….(-) trigger, and violet….(+) positive door trigger wires. I do not understand which goes with which. Have tried several combos and nothing works. From reading it seems I might need a relay. I also have read through the “Hanes” book on the van, but it is not any help.

Any suggestions would be greatly appreciated…..

Thanks,

Tom H.

as old as that van is, it most likely has reverse polarity locks. you will need a diagram to wire those up.  and you only use one door pin wire from the brain. Likely it will be the green (-) input wire.  Just check with a probe on the door pin to see which wire changes polarity from floating to negative when the door is opened.

Power Lock
Power Unlock
Door Trigger
Of course this info needs to be tested with a dmm!
CHEVROLET, VAN, 1995, Door Trigger
Also found behind instrument cluster.

Your door locks on the van should be (+) which means you will need two relays to convert the (-) door locks pulses of the alarm to a positive.

Your door trigger will be (-) so the  green(-) door trigger of the alarm should be hooked up to this. Violet would only be used if you had a (+) door trigger so you don't need to worry about that one.

The blue(-) trigger on the alarm would be used for something like a hood pin.

Hey Guy,

Thanks for taking the time to answer. On the door locks, I have found that the orange wire being (constant) positive , if I take a jumper wire from the orange to the blue- it locks; then when I take the jumper wire from the orange to the black it - unlocks. Does this stil mean it is a negative door lock system?

As stated above by mikvot your van has 3-wire positive doorlocks and you will need to add relays: Relay Setup
Instead of relays, you could use: Polarity Inverter    Relays will be easier to find...you can get them at Radio Shack. You could stop by an alarm shop and ask them if they have a door lock polarity inverter. It converts a (-) pulse to a (+) pulse.

Sorry, you can NOT post a reply.
