Re: Electric choke 12V source
Is this a Holley electric choke? If so, I would NOT recommend connecting it to the wiper power wire. The wiper motor is "hot" when ever the key is on OR in the ACC (accessory) position. So if you have the car off, but listening to the radio for example, your choke is on and Holley's need the car running to cool the element or it will overheat and burn up.
Never connect anything to the alternator field/relay (blue and white) wires. These are not meant to carry loads.
