Is your engine a 2valve or 4 valve? There are wiring diagrams issues between the two.
Customer: replied 2 years ago.
Not sure, but engine vin #2 should tell you I believe. Thought it was 2 valve.

It says vin2 is 2 valve

Ok does the fuse blow if you leave the AC off or will it still blow?
Customer: replied 2 years ago.
Remember ac clutch frozen, totally disconnected, new belt avoids ac pulley. Completely unplugged, even took relay out of ckt to isolate. Eliminates wiring to plug and relay.
