I am now looking for a color wiring diagram. I found a free one when I had the '69, that went with the truck when I sold it.

Source to buy a diagram, which should be better clarity than downloading and printing one: https://classiccarwiring.com/product...wiring-diagram
Another thread, but must have to be signed up to see their diagram: http://www.67-72chevytrucks.com/vboa...ram+color+1968
This ought to be a good source, but I don't see headlights/turn signals?: http://67-72chevytrucks.com/vboard/s...d.php?t=185856

Here is the front of the diagram! This also is about the temperature gauge acting weird which is happening now for me. http://www.67-72chevytrucks.com/vboa...ram+color+1968

The Color Schematic is pinned on the Electrical Page of this forum, iirc.

New Turn Signal Switches run about $50 from the vendors. I've found swapping in a fresh one solves a lot of gripes. Gremlins can chew on a lot of little details in 53 years.
I gave up on electrical temp gauges. The new ones have a different Resistance value. A mechanic said some mumbojumbo about using a couple [1/4W?] resistors in parallel, but, as an electrician, I knew that one would be marginally longer than the other, and create a bias. Putting a Mechanical Temperature gauge in its place is not difficult. Advantages are:
1] Better, more accurate temp indication
2] Works even when power is off.
3] Packrats can't chew thru the wires.
4] Lasts a long time.
5] Looks cool.

Gauges shown are -- Auto Gage Tach on Steering Column. Stewart-Warner Water Temp, Moon Manifold Vacuum, AutoMeter Oil Ppessure.
