Default 91 Civic Sedan electrical issue

So, my 91 civic's driver side tail light is not working anymore. Before today the turn signal would still work, but the brake lights and glow lights would not. Ive checked the terminals in the plugs for corrosion and found none. Used a test light earlier and found that 1 of the 3 "hot" wires is not getting power and im going to assume this is the wire that feeds the assembly given nothing in the light is working. Im not thinking its a ground issue since the passenger side light still works fine and theyre on the same circuit. So...

-pulled the fuse and its fine
-cleaned pins in the plugs with terminal cleaner
-used dialectric grease on the plug
-found 1 conductor in the plug not getting power
-tested light assembly on passenger side (bulbs and bulb harness are good)
-inspected all the wiring in the trunk and found the harness in good shape and untampered with

So, any ideas? Or working links to a wiring diagram for this pile of a car? Im running out of ideas

Try this, I haven't used it in a long time but it looks like the links are still active. There's an EF manual, and you can go up a level and get CRX manuals as well. Sometimes it's easier to find CRX info, and it's all pretty much the same for the common harnesses.

Did you ohm the wire to make sure there is continuity?

Don't have a dmm right now so no. If I get a break from snow removal tomorrow I might be able to test continuity

Interesting use of "ohm" as a verb.

That's what people who work in the automotive field call checking a wire for continuity lol

Life lesson pizza boy- Fabrik8 is the smartest guy on this forum and I'm not saying that to be a dick rider, but you can pick any subject and it he can speak about it in detail at great length. So there is no need for you to explain anything to him

I used to tech and I've never said that....

I also never said that when I was working for an electrical contractor

I call it "faggoting" the wire to measure resistance.

Different strokes.
