Hmmm ... dunno, Carl.. here is a tip, tho... "brown" is considered "earth ground" or "negative" on BMW wiring.. and, since your LT should be a BMW, that is all you really need to know.. just use the "Brown for ground" and the other wire for POWER...

Hope that answers your question...

However, be warned.. I am color blind....

Wiring a GPS thru Map Lite


I am addressing the same issue re wiring to the map light. I sent a PM to another member, and this is what he sent me. Great information.

This post has pictures of an installation using the same directions: http://www.bmwlt.com/forums/showpos...25&postcount=18

Post #12 on this thread shows how the owner drilled an extra hole near the map light to pass the wiring through. If you are only passing in the Garmin power cable this seems unnecessary to me. You can also see the small hole on the left edge (9 o'clock position) of the map light; this is the hole I enlarged to pass my wiring through. Instead I would cut a new notch at the 12 o'clock position. http://www.bmwlt.com/forums/showthr...ht=light+Garmin

The last picture attached to the first post in this thread shows the Garmin power cable routed through the existing hole beside the map light (like mine): http://www.bmwlt.com/forums/showthr...ht=light+Garmin

Here's a thread with good concise directions (several versions) but no pictures: http://www.bmwlt.com/forums/showthr...ht=light+Garmin

Another with no pix: http://www.bmwlt.com/forums/showthr...ht=light+Garmin

I'd recommend that you gently pop the map light from the dash and eyeball it with one of these posts in hand. I bet it will make sense then. If not, send me another PM; I'll take some closeup pix of my setup and send them to you.
THis is what I originally PMed to wcarter:

I ahve searched but to no avail. Can you send info?
