I am looking to installing a glovebox ambient lighting strip in blue and with my car not having it from the factory the wires already there have no power. this is when i decided to wire them up with the sidelights but i am having trouble knowing which wire is for the sidelights as i cannot find any decent wiring diagrams. i am looking at doing this at the lights switch panel (where the fog light buttons are). if anyone knows which colour wire the sidelights are on i would appreciate it greatly. Also a picture may help me alot too thankyou!

The light switch is normally just a command wire, no actual power.

So the wires from the switch carry the switch position to the BCM which then provides the power.

If this is the case how are people wiring things to their sidelights from inside the car? Like where does the feed come from?

Try the fuse board behind the glove box. Pick up power with a piggyback fuse holder. I cant ell you which fuse holder because I have found that every model is different including the same models.

I had my front and rear camers wired into 37 for permanent feed and 8 for ign accessory on a MY2013 Zs tdci but on a My2015 ecoboost Zs there is no wiring built in to the board, It's a case of probing with a meter.

i have taken your advice and they are working great but are a little too bright at night? have you any more tips on dimming them down abit? would a resistor on the positive wire work? and if so what size etc?
