Wich wire/fuse to tap for 12v with headlights on ???

max_k20 · 10-18-2012, 05:33 PM

I've searched on this and other forum and cant seem to find my answer. I'm looking for a wire (or a fuse) to tap into to give power to my boost gauge. Gauge only have 2 wire so I need to tap into a 12v wire that has power only when headlights come on.

I've seen pictures and seem there are wire that are powered with headlights in the front ashtray but it seems to be really skinny wire that I couldnt tap into. Is there a bigger wire (big like the 12v wire to cigarette lighter). Otherwise maybe a mini fuse I cpuld tap into with a mini add-a-circuit ? I swear I've now looked countless thread but none with current info

TL;DR Looking for wire under front cigarette lighter or a fuse to tap into for 12v power only when headlights are one.

Nobody ?

I'm pretty sure there must be a bigger gauge wire bringing power to the leds in the ashtray but can someone confirm (maybe with wire color)

You can tap the wires feeding the LED bulbs in the ashtray unit, they are controlled via headlight switch.

For reference to people who might search in the future.

Red/grey is 12v swiched (with headlight)
Green/yellow is 12v
Brown is ground
