12 DEG BEN 0 Posted April 20, 2007 Can any electrical brain please tell me how to wire up a reverse light signal into my sat nav head unit as it seems to be a requirement and Ive no idea where to begin. I know where it belongs on the iso lead but where do i feed off of the light circuit. Thanks Quote Share this post Link to post Share on other sites
Dec 1 Posted April 20, 2007 I cant remember which pin is needed on the iso plug, but it is really easy to get the feed for it! I just used the + lead from the light for the heater controls! Quote Share this post Link to post Share on other sites
thetino 0 Posted April 25, 2007 If it is a +ve signal that you need, the easiest but slightly long winded way is to grab it from the reverse lamp. Quote Share this post Link to post Share on other sites
12 DEG BEN 0 Posted April 25, 2007 It is a 12v positive im after. Just wondering where I should pinch it from. Probably down the side of the drivers seat If I new the colour im looking for. Was worried about shorting out that system but I guess the bluaupunkt would have delt with that. What colour wire am I after? Quote Share this post Link to post Share on other sites
