Is there an accessory (+v) i can splice into in the driver's door? If so where abouts is it?
I have power mirrors, does the switch run off the accessory feed line?
what are you trying to do? running anything piggyback can cause issues later on.
I need to power a gauge off the accessory line, since the gauge is in the door i was hoping to use a wire already in the door. If that's not an option what would you suggest?
you could allways run a wire through the rubber passage in the door, possibly the safest way to do it
If you are running a gauge in the door would you need to run the signal wires to it anyway?
As above, run a new power feed wire to the door.
If I told you I was a compulsive liar, would you believe me?
Yeah i ran the signal wire through the rubber, but then put it all back together and forgot about power. It's a pain to get out so was hoping for an alternative. All good though.
