Stumped, Fuse #8 issues Options

[srreality]

1973 914-4 - - - - My wipers, horn, cigarette lighter and hot air fan won't work. I'm getting no current at fuse #8. I've replaced the wiper switch, checked the ground, cleaned all the connections at the bottom of the steering column and replaced the horn relay, still nada. I'm an amateur at this, especially electrical current flow. My turn signals work, which to me means I'm getting current to/through that switch. But no current out of the wiper switch with the key on and wiper switch on. What am I missing?

Short answer, yes.
Longer answer, there is no radio listed on the electrical drawings. I believe radio's were a dealer installed option and the easiest way to power the radio would have been off of the cigar ( cigarette ) lighter. That's how mine was wired also.
J-13 would have been better labeled as a power relay for accessories.
Hope this helps explain.
