Plug

Anyone know what this plug is under the brake booster. Has Pink and black
on each side. I seems to be splice into the ECM hot on run.
I looked online for hours can't figure this out. Fixing a few bad splices noticed
this wire has 12 volts when key is on. Thought it was ties in to the mix control on carb.

Re: Plug

Pink w blk = gauges fuse

Lots of ECM-controlled stuff runs off of that circuit

Frankly I'd tie it back and leave it alone if I was working on the car
