The old wiring is so old (and painted over by the p.o.) that I can't see the colors of wires going to this part circled in orange (you can see a picture at: http://www.picturetrail.com/gallery/view?p=999&gid=8919034&uid=4216428&members=1 Based on the wiring schematic in the shop manual, I'm guessing that is part is the headlight dimmer switch, anyone know for sure before I wire to find out? Thanks | | |

most of the time you can't see the wire color right by the part anyway on wiring so old, but you can frequently strip the outer covering on a bundle and find the color further back where it was protected

I don't want to be a Christmas Grinch, but If you don't know what this part is just by looking at it, I sure hope you have a good helper when you start ripping wires out. Even seasoned veterans get confused when faced with a wire loom the size of a German sausage and instructions written in Cantonese! Good luck, this wasn't meant to be a "humbug".

I zoomed the pic and still can't see the shape for sure. I may just be a bad angle but it looks too close to the steering column to be a dimmer.

How many wires connect to it? They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | |

I got quite nervous..the Sharks wouldn't commit to the fact they were 100% sure it was the dimmer switch. If that was the case, in light of my previous post I would have to commit Hari Kari.
To avoid that unpleasant task, I hustled down to the shop where my naked cab rests on a dolly. I am now 99% sure the item you have circled in your picture is the dimmer switch.
If I am wrong, I will send you a case of Jack Daniels post paid, post haste! Feliz Navidad.

I thought the P.O. might have added a terminal relay of some type because I thought the dimmer would be lower on the firewall, but it is the dimmer. The stop switch is actually more towards the center of the firewall and the "fingers" on it are the bullet connectors (I had re-wired that switch previously when I wired a turn signal indicator to the rear lights).
I've seen lots of posts asking about putting in new wiring harnesses, I'll have to put in a post with pictures once I complete this. It's actually going pretty smoothly, the only difficult part is I can't "cheat" and use the "color coding" on the old wiring harness since its faded/painted over and the shop manual wiring schematic doesn't show the color coding anyway!
Merry Christmas to everyone! | | |

Merry Christmas to everyone! Happy Ho Ho back at ya. If you go here you won't have to worry about the color coding, correct wires & connectors.: http://www.ynzyesterdaysparts.com/

There's one page in the factory assembly manual that was invaluable in showing the wiring of the headlight switch, instrument clusters and ignition switch.
You should have seen the condition of the original wiring, there was more bare wire than you can imagine, and yet everything worked except the right high beam headlight!
Thanks everyone for responding. | | |
