CJ Radio Fuse Wiring

Have 78 CJ5. Radio works but memory on radio does not. Second power wire is not hooked up. I know it needs to go to a fuse that is live when ignition is off but not sure where to connect it. The main power wire is female and hooks to fuse box where is says radio. The second power wire is flat male post. Not sure how or wear to wire it up. Spent a lot of time getting this old fuse box and all electrical working so I want to do it right. Help. Thanks

Cut the end, splice in a line going to the battery pos side, put a inline 10 fuse and call it done. Remember the old radio didn't need it so I don't believe there is a constant power line except maybe If you have the clock

If he doesn't have a clock, the connection is still in the fusebox so I would connect it there.
If you have a clock, Look for a fuse adapter to connect it.

I have a clock that does not work. I'll see if I can disconnect it, change the male terminal on radio to female and plug it in.

Am I correct that there is no female terminals on the fuse. Box. I can't find anyplace to plug this flat male terminal in.

John the 78 fuse boxes only has male contacts. What do you mean by fuse adapters?

I think the 78 still has glass fuses so these are handy

Fuse Tap, Fuse Taps For AGC Round Glass Fuses NAPA Part: NW 785131

Still all male connectors. You will have to change your terminal.



For reference for other types of fuses

The wiring for the 86 CJ7 cigar lighter should be in the harness already even if you don't have one.
It connects to the backup light fuse.
