So I’m taking off the holly 750 that the previous owner put on the ‘71 318 that is in my ‘66 Barracuda. My buddy gave me a street demon 625, but it has an electric choke. I’ve read that I need to splice it to the dark blue wire, so it will only get power when the key is turned. Well, like a bowl of bad spaghetti, my harness is a MESS! Can anyone point out which wire I’m looking for? This is my 1st classic car, so this is all new to me. Let me know if I need to snap any more pics. Thanks in advance.
