Default Hardwiring GPS/ other 12v goodies.

Allright, I'm hardwiring all my stuff, and have just one question. My GPS cord has 3 wires (black, red, green). What is the green wire for?

What model GPS?

Green is most likely switched +12V (IGN source).

Don't forget to install a 5A fuse(s) on the hot side(s).

thats the horny wire,like M&Ms...

black-ground
red-constant make sure you have a fuse, that way if something goes wrong with your setup it wont fuck up the GPS
green-horny..jk, i dont know exactly but i believe its the accessory try just the red and black connected, then add the green if necessary

Well, I don't know what happened. Red and black (with a fuse on the hotside) did nothing. Green connected to + fried the fuse and, I'm pretty sure my GPS is done for.

Again, what model GPS?

Did you have a fuse on the green wire when you connected it to switch +12V?

edit: The only other scenario I can think of is red = Switch +12V, black = ground, and green is a NMEA data string output.... but that is a serial connection and should require two wires.

There was no fuse on the green wire, no.

This was just clipped from the cigarette plug, no funny business wires.

could have fried the unit... =( Always have a fuse on a hot lead.

Sounds like the GPS cigarette plug had a voltage regulator that knocked the voltage on the green wire down to 5V or something like that.

It would be a good idea to splice it back together as original, and hardwire in a hidden standard 12V socket (can be found at radio shack). (Don't forget to fuse the hot lead on the socket.) As a side bonus, you would still have portability if needed.
