Default 1966 catalina ac fan issue

Anyone have a wiring diagram for a 66 catalina bonneville ac fan wiring? My AC nor my fan will turn on, it just quit. I went to change the relay , got one from Ames. My current relay has 5 posts, there replacement has 3 posts.. then the factory plug was not used, it was 3 wires and a ground wire all wrapped in what looked like factory tape, they were plugged into the relay..anyway that did nothing. We jumped the fan to see if it was working and it works fine.its like its getting no juice from the dash 3 position fan switch for the fan and the compressor..anyideas? Everything looks plugged in, fuses underdash are fine etc..thought if I could get wiring diagram it would help.

Check the inline fuse that is connected to the back of the alternator. 99.9% of the time, that's the problem.

Is that all wrapped up in the red tape off the alternator?

Not sure about the red tape, but it's a 30 amp glass fuse in a clear/white fuse holder. Lots of heat and it gets pretty crusty after 55 years.

I took all tape off the wire cluster going from alternator to where it splits to the relays, no inline fuse on this one..
