What are these plugs/wires for? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I can't seem to find these in the wiring diagram...

The one on the passenger side looks like it broke at the end to wherever it's supposed to go and when I pulled it apart it looked like it had a glass fuse that rusted and caused it to break. There is an identical plug/wire on the driver side.

1970 C10 but it's not original and had lots of DIY mods over the years before we got it and a mad scientist did all the "wiring".

This is going to the voltage gauge? Why the two plugs/fuses on both sides of the truck?

It's for an original Ammeter not Voltage meter. The Ammeter senses the difference in voltage on both ends of the circuit. If you're truck still has an Ammeter then you'll need both fuses. If your truck has been retrofitted with a Voltage meter then this circuit should no longer be hooked up or needed.

Both use a 4 Amp fuse for the Battery Gauge (Ammeter). They both go directly to the gauge and nowhere else.

If it is corroded or you can't get the broken fuse out, you can replace it with a universal inline fuse holder & a 4 amp fuse.

I’d soak it for a few days in WD-40, then grab the remaining metal with smallest needle nose pliers ya got in your toolbox, don’t destroy the rubber boot
