If I connect the 12V battery (+) to the 2 red wires from the main wiring harness and the battery (-) to the chassis ground, will the electrical system power up when the ignition key is in the ON position?
The main harness is plugged into the relay board. Neither the alternator, ignition or injection harness are plugged into the relay board, but all the round relays are in place. By electrical system I'm referring primarily to windshield wipers, headlights, and lights. I want to make sure they work before installing the fuel tank and engine. |

That sounds like some other type of short... as far as I know there's no fuses going between the battery and the ignition switch.
In terms of what P goes to, that wire goes over to the turn signal assembly to provide power to the parking lights when the key is turned off. (With key off you can move the turn signal stalk and light up one side of the car's parking lights.) |
