The tach wire passes through the fuse block, I believe thru the 4 wire connector for the wiper motor and it's gray.


Yes it is gray with a trace. In the early harnesses, it went to cavity 20 on the bulkhead connector. In 73, it went through a grommet in the firewall and cavity 20 went to the A/C compressor.
Still looking for the hole it goes through.
