What is this wire for?
What is this wire for. It’s brown and goes through the bottom left space on the firewall plug. My truck is a 1972 GMC with a 3 hole gauge cluster.

Re: What is this wire for?
72 service manual wiring diagram shows 20 brn/wht wire in that position for TCS, transmission controlled spark system. I think I see a faded white stripe on that.
