78....what are you working on? The Monte. Post what your working on and I'll see what IO can do to help you out. I would say different years and models have different coding but I may be wrong.

Its the harness in my 1958 Volvo.Thing is I'm not sure what its out of.I'm told an 80s chevy truck but it has glass fuses,so I'm thinkin its older.At the time I needed the hot for the wipers and heater but I found them.So far I've got most of it now,I've had the fuse block out twice and every harness in the dash untaped and I rebundled everything individual so I know whats what.
I've got one plug that I have no clue about thou.It was hangin under the dash when I bought the car so it obviously had an intended use.And also a problem with constant hot to my break lights.But first I've gotta try testing the switch thou.

Also any clue how to wire a third break light up??I've got one,it has a hot(red) and negative(black),then I've got the relay box thingy for it it has one yellow and two green wires.I'm guessing this box is what makes it seperate the signal lights from the break lights,right??
