That sender in the first pic is not for may dash gauge, I my oil gauge sender is located by my oil filter. Yes, I am keeping the A/C. So, I can delete all those wires and run the green wire to the high side solenoid? Thanks, David
This is what I did when I was trying to figure out what to delete. I went from an early 350 to a 350/330 crate motor with the serpentine setup. The original ECM harness was still in my car but all but two wires were cut. I had the car running, cut the two remaining wires and the car was still running. At that point I figured I should rewire everything for the motor.
As you can see in the first picture the plug for the AC was toast. The piece that went into was a melted mess wrapped with electrical tape. I got a decent plug from a local junkyard and put all new terminals on both sides. If you notice the four wires you can see the solid light green. Red was power, dark green and black went to the compressor. In the second picture you can see the light green winds up in that flat plug. I was told its for the high idle. Thats where I put it. Does it work ? Havent tried it yet since the AC isnt quite finished. I hope it does. LOL When I have the AC charged I guess I'll know.
A lot of the stuff in the second picture got deleted. The rest was redone to the bulkhead connector on the firewall. Im sure yours will be way more wiring since you went with the LS. Thats the main reason I went with an old school SB. Wiring is something I dont like to do.
