77 wiring diagram...

[ryoken]

Anyone have a diagram on file for the underdash on a 77? or close to that? maybe pre 80...

I have the factory one for my 87 which has been a godsend, but I'm incorporating some 77 parts in my build... Mainly interested in the column turn/hazard plug at the base of the column and how it ties in and feeds thru the junction/fuse block, hazard/turn flasher, etc. Consists of 10 wires.. Horn is black, etc...

Ignition switch plug to fuse panel would be handy too, but not as needed.. I'm trying to avoid a couple hrs dorking around with a meter and continuity tests...

As always any help appreciated...

I have one...

Turn signal switch

horn = black
left front lamp = light blue
rt front lamp = dark blue
hazard warnings = brown
flasher = purple
left rear lamp = yellow
right rear lamp = dark green
stoplight switch = white

My diagram shows only 8 wires! (?)...sorry,I have no means of posting a picture of it..probably couldn't read it if I did-I had to use a magnifying glass just to read the color codes..

Ignition switch has 8 wires too,
orange,
purple/white
brown/white(gauges only)
dark green (not used with gauges)
pink
red(2)
brown
tan/white


if you need more info let me know--not sure if I can read the printing on the ignition switch section of my wiring diagram,but I'll try to help if I can...

Awesome Bob, that just confirmed what I had worked out....

Those last 2 where a pink and black seperate from the other 8, they ran to some tabs that did nothing on the t/signal, so I'm not worried about em...

Thanks again...
