Need some electrical help with my ‘68 Plymouth Valiant 100

The red arrow points to the actual fusible link.

This is what it looks like not attached to anything. (NOTE: there is a tab on the wire that says FUSABLE LINK) in your case the wire looks black and the tab looks yellow.

You need to understand that the entire wire is a fuse. the TAB is only there as an indicator.

I know it has been mentioned before but terminology means a lot.

This is The "Bulkhead" all the wires inside the car connect to it under the dash

These are the Bulkhead Connectors. all the wires in the engine compartment and the forward lighting are connected to them. They connect to the bulk head.

There are NO fuses in the Bulkhead EXCEPT the Fusable Link which is attached to it.



This is the "Fuse Block" it is mounted under the dash by the Emergency brake. SOME fuses are powered some are only powered when something is on

Thank you so much for this. This just helped a ton.

I’m having some confusion regarding the VR again, because I’m looking at some original VR’s and some are adjustable, but I don’t fully understand if mine is, or how would I exactly know it is? What is different on it?
