Mystery Firewall Wire.
I noticed this factory looking plug attached to a brown/white stripe wire sticking out of my fire wall engine harness. I'm not sure what it goes to. It looks like it's right next to the large purple wire when it goes through the fire wall but there is not a wire listed there on the wiring diagram that I see.
Does anyone have any idea on what this is for? 1972 k2500 350 4speed. Posted via Mobile Device |

Well it looks like it won't let me upload the photos. I'll try it on my computer. |
