1976 wiring diagrams 911s? specifically horn related!

hey all -

been looking all over the place and I cannot find a wiring diagram specific to the 1976 model year 911s.....there are 1975 wiring diagrams, and 1977 wiring diagrams, but is the 76 a transition year that did not get well documented?

I have no owners manual, Haynes leaves out the 76 model year as far as I can tell, and a search here has not helped....

to further complicate matters, the car has been converted to a 1989 3.2L power plant, so lord knows what the electrical permutations were to get that to work?!?! Dink Farmer did the conversion, who has a pretty good reputation as far as I can tell.

Trying to get the horns to work, flying a bit blind at the fuse panel. I have 'clicking' in the relays when the button is depressed, but no noise from the horns. I swapped the relays around - same result. Jiggled all the wires at the horn connections - they are cruddy but appear to be solid on the attachment points.

The later horn diagnostics are somewhat useful, but I'm not sure what I'm working with - they do not appear to be the 964 horn configuration judging by the pics....

any help appreciated - as always!

cheers

tom
