I fit ALL THE RELAYS under the dash ( hidden by kick panel ), and took the power from ammeter stud, alt side.

didn't cut a wire, simply removed the terminal from original foot switch plug, instaled on relay plug, and run back the other wire ( signal ) on same color between foot switch plug and relay plug with new terminals, so you'll never see a relay anywhere or diff color wires, or splice anywhere.

made teh same on each speed of A/C-Heater.

relays are away from engine bay heat, dust, grease, water and rust caused by elements. and won't tell any splice or added device on engine bay
