Wiring diagrams 1976 911? Specifically horns!
 

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

ugh, apologies, wrong forum. sigh

Horn wiring diagrams........
 

Tom,

Where have you been looking for the wiring diagrams? The wiring diagrams for the horns circuit for '75, '76, '77, and SC's ('78-'83) are all identical. They have not changed a bit. Check if you get power to the relay and the relay is working.
