Thanks Otto, I think the terminal block is ok as it has not been touched and perhaps the original fan is going out for a smaller unit.
The terminal (spade) numbers on the original relay would have been nice to know. Maybe its a a special configuration on the relay? Could be mine is just trash of course.
I do have the original switches in dash. I am not going to use the fogs though, I am replicating "S-04516".
I have had a few early 911's (69, 70 and 72) and am familiar with the later fresh air system, I just could not remember how it was on the SWB cars, last time I had one was back in 1996.
Have some 150+ photos during the "makeover" (+ some for reference) here:

In the end of the album ( page 7 & 8 ) there are photos from when I started taking it apart, must be 3, 4 or even 5 years ago.
