Lojack wiring question...
Hey everyone.
I think I just stumbed across the Lojack box in my car.. but I noticed that one of the wires isn't connected!
The lojack box has the following connected:
1) Antenna
2) Red/Black wire to a small battery pack
3) Black wire that's grounded.
4) Red wire that's not connected to anything.
Logic would dictate that the lojack can't just run off a small battery pack, so I'm guessing the red wire should be connected to a +12v source.
My question is.. if I connect the red wire, will there be any negative side effects? will it set off the lojack?

Small battery pack is probaly an back up battery just incase the theives diconnect your main battery.So I'm guessing the red wire is for the 12v power soure?

Gonna answer my own question..
So I ended up connecting the red wire to a +12v source. It didn't set the lojack off. But at the same time I have no idea if it's working since it doesn't have anything to indicate it is.
