I'm looking for the best place to tap for switched power. I'm running a few different relays for different things and wanted a few ideas on the best locations.
There is a set of four wires under the dash that Ford put there for customer use. I think two of them are switched power. You can get to them on the motor side of the firewall and choose the one you need.
does the 7.3 even have customer access wires?
the ones i have seen and read about aren't terminated on either side they just get you through the firewall
you really trashed this whole post with your selective edit
please delete all of mine so it doesn't get taken out of context with the ones your selectively ( post 5 is a joke ) removed that yes they were all technical
