Tracing wires & horn questions Options

[narino]

With the warm weather I've spent the last few days fixing wire connections and removing extraneous wires by the PO. A couple wires have me stumped, hoping for some help from the hive mind.

#1 - I have a heavy gauge red wire that is coming off the alternator, that the previous owner spliced into and ran through the longs to the hot terminal by the fuse box.

• Is this red wire from the alternator stock? I couldn't find it on the wire diagram.

#2 - The PO ran heavy gauge red wires through the longs to the hot terminal by the fuse box.

• I do not think this is stock, from what I've read there were no wires in the longs. I've only found reference to the charcoal canister lines in the longs. Could someone confirm whether this is correct or not?
• If these lines are not stock, then what originally used to go through the hole behind the dash, where these lines currently run? Pic attached for reference.

#3 - I bought some pilot fog lights and went to install them and saw my horns are in the way.

• Are these horns stock?
• Before I start tearing more things apart, are there other mounting points to relocate these horns away from the grilles?

Once I get these hot wires figured out I'll feel safer trying to start her and get her back on the road.

Thanks in advance!

The headlight switch is a switch--or rather, several switches in one housing. With one exception, the pins either contact other pins or don't, so the resistances you are looking for are "infinite" (no connection) or "zero" (dead short or close to it).

The one exception is the instrument light section, which has a rheostat--a variable resistor.

All the below is from the 74 wiring diagram; other years may have differences. The headlight switch has three positions; in all the way, out one stop, out all the way. I have labeled those positions 0, 1, and 2 below. (Though I could have those backwards.)

Pin 15: Should have no connection to any other pins in switch position 0 or 1. Should connect to 56 and 56K (only those) in switch position 2.
Pin 30: Connect to 30b in switch position 0. Connect to pin 57 in switch position 1. Connect to 58L, 58R, K in switch positions 1 and 2.
Pin 58a: No connectivity to any switch other than 58b. Variable resistance from 58a to 58b depending on knob rotation.
