I'm trying to find a place to tie into the electrical system that's energized when the key is in the ACC or ON position. I've looked at electrical drawings and I've found a couple of spots that work 'electrically' but would require me to cut into a harness. I'm looking for a much less invasive solution if one's out there. This spot will only be providing the electrical signal to energize a relay and power gauges, and the main line power for the pump will tie right into a battery terminal so it doesn't have to be down stream of a large fuse necessarily.

Thanks in advance.

 

Factory switched power with the ignition to 'ON'....though not sure about 'ACC'. Takes a spade connector......
