Re: Can You Identify This Under Dash Wire?
That's kind of a big draw. Best to use a relay, pulling power from the battery terminal of the solenoid. You could trigger it from the positive terminal of the coil. If you need to use a trigger source inside the car, the center, screw terminal of the ignition swich is hot when the key is on, but also in the ACC position if that's a problem.
Don't forget an inline fuse, maybe 15 or 20 A, preferably located close to the battery end of the wiring (to protect more of it).
