I'm blowing fuse #8 on a Late - 72. Turn key and POP. Remove relay (914rubber new relays) and all is good until I put the relay in then POP.
Checked Wiper wiring and is correct. Disconnected the blower, cigar lighter, and horn still get the same. Which means if I'm reading the diagram correctly it should be in the wiper circuit? Could it be the motor itself? Last thing I want to do is remove everything to get the wiper out.

Idk what #8 is, but I too am having trouble with 914 rubber relays. I put his new relays in at the headlight motors and I keep blowing the fuse when I switch my headlights on. I fiddled with the prongs on the relay to make better contact. I was running out of fuses so I switched back to the original relays since I was running out of fuses. The old relays worked well. Headlights go up and down. The fuse does not burn out. Try an old relay

Disconnect the WW and any other item on that circuit. Then add them back in one at a time until you pop a fuse.

Oops. I read your post after posting. That relay is easy enough to diagnose w/ VOM. LUK where it's grounded.

Thanks guys. So I disconnected everything and the first thing I plugged in was the wiper switch and...POW. Is it safe to say the wiper switch is the culprit?

@jeffbowlsby - any thoughts?

pull the wheel and pull the switches and make sure something isn't grounding itself to the steering column shell....

I pulled the steering column switches and have not gone through them yet. Any have a diagram of the actual switch wiring? No pinched wires but I did replace it and maybe got the wires in the wrong spot.

I was just having problems myself with the number 8 fuse.

I found this which was be helpful:

For my case the blower fan was gunked up and the wiper motor was stuck.
Removing the power going to those fixed my problem.

See the site I posted above.

Steering wheel and ignition diagrams there as well, very helpful.

By the way, I got the part and installed it already..thanks

That link should prove to be very valuable! Thanks @mueller !

Glad to hear the part showed up and is installed.

Thanks again, Brad
