battery constant at radio

I'm not getting battery constant at the radio. I have switched power the illumination and dimmer wires work as designed, I just don't have battery constant. Where should I start trouble shooting?

Radio fuse. Or just run a new wire assuming the other one isn't groundig out somewhere.

Garage
generally the pink wires are always hot and supply the dome light and the radio memory

Pretty sure it's fuse #2, about in the center of the block

Sometimes it's easier just to run a new wire.

I jusr stripped out a hacked up wiring harness and want to keep this one clean, so ill work on trouble shooting. We will see how much that takes. Worst case run a constant feed

Ok, new findings. I traced the wiring all the way back to the fuse block. I have continuity to, and through the fuse block. That means something on the engine side of the harness is incomplete. I also discovered that all the under dash wiring also runs off this same circuit. Ok, my next step is to verify that there is in fact a pin that comes from the engine side of the harness into the fuse block in this particular position. Is there a fuse under the hood that would affect just the interior courtesy lights and the battery constant to the radio but nothing else?

I have the same issue. THe constant power is the yellow wire. I gave up when I could find no issue's with the wiring and ran a new one. Throw a 10 amp fuse in it and be done.

1995 YJ. 2 inch BDS Spring lift. 1 inch shackle lift. 1.25 inch JKS Body Lift 33x12.5x15's. Engo 10,000 pound winch.

I'm too stubborn. The dash wiring is pristine. No cuts, nicks, dings, pinchs. Nothing. Next step this evening is to check the engine side of the wiring. Starting at the bulkhead connector.

Also a side note. The yellow wire is referring to is for the radio harness adapter. The dash wiring, at least on my 93, is pink. This shares power to the under dash lights.

I dont have an adapter. Mines a 95 but then again I am colorblind so that may be a factor.

Problem solved. There's a tiny mini fuse tucked in the corner of the under hood fuse block labeled IOC. This apparently is the fused link to the constant battery/under dash lights. Ill post a pic later.
