Alright so you have blue, red, and green so far. Blue and red are the relay contacts, that's fine and will work on either the starter or fuel pump circuits.

What you need to determine is what that green wire does. It's obviously an output from the controller to the relay, but is it sink or source?

Sink would be where you provide +12V directly to the relay coil and the controller would GROUND that green wire, which would be connected to the other side of the coil.

Source would be where you ground the relay coil directly, and the controller would ENERGIZE that green wire with +12V.

Once you figure that out, you can wire it just like it says but tie into the fuel pump circuit near the inertial switch instead of the starter relay.

 

Ok I still am not sure what the green wire is for, however I did a continuity test between the red and blue and it zeros out, so they are

connected. Since I can not get into my photo bucket account I will describe the layout of the relay. I hope that will help. This is a five pin

relay but only four are used the top pin or front pin however you want to look at it, is 87 and is not used the left pin is 86 and is the green wire,

the middle pin is 87a and is the red wire, the right pin is 85 and is a white wire the jumps over to the bottom pin which is 30. So the 30 pin has

white and blue. I don't know if this helps you help me. And really appreciate your help!

 

Alright, thanks. Got your configuration figured out.

Green wire (Terminal 86): Wire this back to the GPS control per the destruction (instruction) manual. This is sink logic so your controller will GROUND this wire to trigger the relay.

Blue & White wires (Terminals 30 & 85): Connect the blue wire from 30 to key-switched +12V power, and leave the white jumper in place. This powers the relay common (30) as well as the coil (85).

Red wire (Terminal 87a): Connect this to your fuel pump circuit downstream of where you spliced in the blue wire. This is relay-switched power to the rest of the circuit you spliced in to.

Aw crap, I can't do ASCII art here, the forum automatically shoves all new lines to the left edge. I'll try and make one.

And you're welcome! Hit my button to say thanks!

 

Also which wire on the fuel inertia switch would be the one I need to cut, red/yellow or the green/yellow looking at the wiring diagram it looks like it should be the green/yellow

 

Here ya go. Sorry bout the black background (if you wanted to print it), I drew that in software meant for designing industrial HMI's (because I don't have access to the CAD computer at the moment, and I HATE MS Paint!) so if I'da taken the background out it woulda been just grid lines all over.

As for which wire to cut, trip the switch (a small slotted screwdriver in the slot at the top will do it) and see which one still has power on it with the ignition on. That's the one you want to splice into.

 

Thanks a bunch, If I ever get up to SW Florida, I have to buy you a beer. I will let you know how it works out.

 

You're welcome!

 

Works like a charm, took about 45 sec to send the signal and run out of fuel. Thanks again

 

Does your GPS tracker have it's own UPS? If not, and the thieves rollback it, or wheel lift it, and disconnect the battery (if they suspect a tracking system) that would suck.

I only ask because I don't know--maybe they all come with UPS's (Uninterruptable Power Sources--big word for "dedicated battery").

But since you're going to these lengths, I thought I should raise the issue.

Congrats to you and all who contributed to your successful installation--I'll log this thread for future reference!
