am getting ready to install a volt meter on my F3. This will be attached with a bracket to the back side of the instrument cluster-have that all worked out.
am not looking to discuss whether I need a volt meter or not, or why I want one. Decision has been made.
Looking for a switched source of power easily accessible. I have no problem fishing wire a foot or more.
Not interested in removing a lot of plastic.
Have found a factory wire (a wrapped pair actually) with a factory label that says " Customer Accessory Circuit".
It's under the left fuse box and visible with the frunk removed.
Want to know if anyone knows what this circuit operates and if it is hot with the key on? I can test it myself but hoping to find an answer.
Am hoping to get some good ideas.
