Wiring an accessory

Hello All,

I will be installing hydraulic anti-theft devices in vehicles(new company) and I haven't actually done one yet. My question is about the wiring of this device:

I have 5 wires, 2 of which go to the battery(red and Black)

I have 3 other wires(Red,Green and Yellow which I believe are sensor wires of some sort. The Red wire is to be connected to ACC so when the Ignition is switched on, the unit cuts it's own power. According to the documentation(which isn't very clear) I just take a "Fuse Tap" or just connect it somehow and connect the Red wire to the IGN/ACC fuse.

The Yellow and Green wires control the auto locking feature and is to be connected to the back side of the rubber covered door switch. When the driver opens his/her door after shutting off the engine, the unit automatically locks all wheels. The Yellow and Green wire do the same thing and I am to only use one of them, Green or Yellow depending on the vehicle.

I have seen one of these installed 1 time and the guy removed all of the plastic molding along the floor board just under the door to run and attach the Green wire to the back of the door switch.

I am trying to eliminate the removal of this plastic molding to save time and I was wondering if I could just "Fuse Tap" the Green(or Yellow) wire to the fuse that controls the door switch. I think that fuse includes the dome light and some other things as well. This would save time and the chance of damaging the molding and also make the job much easier and more pleasant for the Customer.

Sorry for the long post but am I missing something here?? I think that since the Red, Green and Yellow wires are just sensor type controls for the unit to auto cut power (to ACC) and auto lock the wheels(to back of the door switch) when the drivers door is opened, that I should be able to do the Green (or Yellow) wire (to fuse that controls the dome, door switch and other) the same as the Red(to ACC) in the fuse box????

I hope this post is clear enough, I tend to ramble on a bit?

Any help to answer this question would be greatly appreciated. Thanks a bunch.

You need to find better instructions or hire a professional installer since this system could cause a multi-car pile up if not installed correctly. You also need to get a good wiring diagram for the vehicle you are trying to install this in.

The green and yellow wires are likely offered for you to use one or the other depending on if you have a "ground when closed" or "battery when closed" door pin system. You need to determine accurately which system you have and then understand which wire from the lock to use. You cannot just tap to the interior light fuse as that fuse likely has power at all times. You need the door switch output that toggles only when the door is opened or closed.

Considering the possible safety ramifications if this system is not installed correctly, you need to either be prepared to install it correctly, which may involve removing body trim panels, or pay someone who is willing.

Hello Rod,

Thanks for the reply.

I agree with your post %100 that the installation is absolutely critical and it must be done correctly and it absolutely will be. These wires, the Green and Yellow are optional and don't even have to be connected. The system will work as usual but without the "Auto-lock" option if either one is not connected. Just trying to save time and possible mistakes done by our Mechs when removing the trim panels and was just thinking there must be a better way.

Thanks for the reply and the info. I will get better documentation from the manufacturer of this device.

Cheers,
