Hear is a

My wait to start light worked fine when it was in the 95, but nothing on that little square of diesel option lights works now in the 76 cab. I don't get it, all I did was unplug and replug everything. This is the only thing that don't work on my truck now. I was gonna wait till it gets wormer out and post a threat on it, but for now I will watch HARDTIME's post.


My baby is a one of a kind.
1977 I bought a new 76 F150 club cab.

Nothing stock left on her and not a nut, bolt, hose, or wire on there that I didn't put where it is.
