Hi,
I believe this was discussed a while back but I haven't been able to find the appropriate posts. I intend to install a rear 12V cigarette lighter outlet (if I am refering to it correctly) in my 97 Disco I. The rear trailer wiring harness has in addition to the the center bundle of wires going to the harness plug two additional single wires (with removeable red end caps). One single wire is purple color with a thick brown stripe running down it's length while the other is green in color with a thick brown stripe. Can someone confirm which of these single wires is the 12V positive lead? I assume once I find the 12V positive lead, I install a 15amp in-line fuse in it. For the negative connection (in back) I also would assume I can use any chassis screw (like near the rear tailights) for the "ground" connection? Sorry for all the basic wiring questions but I want to avoid potential problems. Thanks in advance for your help.

Dave,
I did this a year ago and have found it very handy. I don't recall the color of the wires but the one lead is always live and the other one is "switched". If I remember correctly the "switched" lead is connected to the reverse lights. If you have a voltmeter check the wires with the ignition off to find the live one. If you don't have a voltmeter any 12V light will work. If you tap into the other wire your auxilary outlet will only work when reversing... After that proceed exactly as you stated above.
good luck,
jeff. |

Hi Jeff,
Thanks for the info. My voltmeter died a few months ago so I haven't had the chance to pick up another one. Guess if I pick the wrong wire (of the two single wires), the worse that would happen is there would be no current when the vehicle is not in reverse. I just didn't want to blow any fuses or cause a short by picking the wrong wire of the two. I assume the 12V lead (the correct wire of the two) as mentioned above is "live" all the time, even if the vehicle is off? Is this correct? Anyhow if you (or anyone) does recall which color single lead (see above) is the 12V one, at least I'll be able to re-confirm it. Again thanks!

Dave the wire you are looking for is purple, the other wire will be either green or brown and is live only when you are in reverse. There is actually a section in the owners manual that talks about it too. If you have any trouble please respond, I did this install a few weeks ago and it worked fine. |

Carter, I appreciate you response. I haven't attempted the install yet (which I hope to this weekend) but one of the two wires is purple (with a brown stripe) and the other wire is green (with a brown strip also). I'll assumefrom yours and Jeff's response that it's the purple wire thats the full time 12V wire. Do you know if it outputs 12V even when the vehicle is completely switched off? What did you use for ground (thats near trailer wiring harness?). Thanks for the help!
