    It's an orange wire that should go to the fuse box. It should be marked as "Bat Fused" or something similar.

    One wire from either prong on lighter (doesn't matter which one) to power source at fuse box, either ignition hot or constant hot (I use ignition hot). There should be some open prongs on the fuse box to plug into. Make sure the other wire from the cig lighter is to ground. Use a test light to find an ignition hot prong in the fuse box.

    It does matter what prong you use for "HOT" on the back of the lighter. One is for the "GROUND" and one for "HOT". I had to try to hook mine back up with the lighter still attached to the dash and missed and got the wrong prong and kept blowing fues. I thought I had the correct prong until I finally removed the damn lighter from the dash. DOH, wrong prong.

    The rule for cig lighter housings is:

    Center = +12VDC ("hot"), outer = ground or no connection.

    The outer prong on the housing grounds to the ashtray/door assembly, which is chassis ground in itself. Connecting the "hot" wire to this prong will blow fuses, as previously mentioned.

    Don't think it mattered on the aftermarket one I bought, if I remember the package directions correctly. Of course, I do have CRS, so maybe I don't remember correctly, or at all /forums/images/icons/crazy.gif. Good to know the rules however.
