This diagram shows the 12 gauge brown wire going down to the fuse panel and the black arrows point it out. The brown/white stripe is just below it and it runs to the inside of the firewall block.
The 12 gauge brown ACC wire goes to the back side of the fuse panel and powers the wiper,TS, heater, and backup light fuses. Hot with key on.
This is a lousy picture but it's the only one I have.
Your key switch shows a small red wire with the main red power wire on the same connection. i don't remember what that powers but it is full time hot.
