WIRING DIAGRAM

The VERY first thing we need is the year make model of whatever you are working on

Do you have ANY power? dome lights, headlights?

PLEASE do yourself a huge favor and get rid of that "scotchloc" connector. Those are JUNK.

I do not understand your question, "red wire to battery?"

The ignition switch (if this is an old Mopar) gets power to the switch from a splice in the BLACK ammeter wire up near the cluster. That power is NOT fused except for what is called a "fuseable link" out in the engine bay, and they are VERY poor protection.
