I want to set up two relays at the front of the engine bay of my Aus-spec 1990 NA to run air horns and driving lights. The air horn compressor has been installed in the void under the drivers side head light. To get power to the relays, I could run a heavy 12V wire to the relays from the starter motor terminal. Does anyone have any suggestions on a more convenient place to tap into 12V supply near the front of the engine bay? thanks Paul
