I have a 1972 1.7 and I am trying to undo (or get back to original) some PO work. I am focusing on the interior fan slider unit. It looks like the PO tried to by-pass the fan slider with a switch. Does anyone know where I could find a wiring diagram that would show this area?

Thanks, Ross

These should help:

I believe you want the '71 part II.

Also in the Haynes service manual you should have in your collection

All 914/4 wiring harnesses are here too:
