On my '86, the PO installed a 350. While he did what looks to be a reasonable job, I'm still finding issues and am trying to clean them up. I've been trying to adjust the choke on my Edelbrock 1406 with no success. Today I put a meter on it and found no voltage going to the choke. I traced the wire and it eventually ends up somewhere in the dash. Choke light maybe? Regarding the light....it comes on when I'm cranking and then immediately goes out upon starting, regardless of outside temperature. I found another thread about the choke wiring and it says the wire should be attached to the oil pressure switch. I have a mechanical oil pressure gauge and I found where it attaches to the engine and right beside it, there was what I believe to be the switch. The problem is that it is so buried back there behind the distributor, I have no idea how I'd get in there to splice it in. Being inherently lazy, I'm looking at what might be a better choice for switched 12V. I've read where people have spliced into the wiper wiring. I put the meter on the wiper wiring and found all three wires registering 11.8V. This was the harness going into the motor. The colors were white, gray, and purple. None registered hot with the key off. Would this be a good way to go? If so, does it matter which color wire I use? If it's imperative to use the oil pressure switch, any hints as to how to get back in there? I'm an old fart and my body doesn't twist and turn as it might have 40 years ago. I do appreciate any ideas you folks may have.....and MERRY CHRISTMAS!
