No body does QA anymore! My company laid them all of and is having the developers test their own code. We recently had a town-hall meeting with upper management to discuss the increase in escaped defects to production and the root cause...

Hey Guys, Looks like I inadvertently deleted the images of the exploded view of my 280Z horn I am restoring. Based upon scouring the web, I've assembled them in the order I believe is correct. See image below. Can anyone confirm? Thank you! Cheers! ~Matt

Update: I took my remaining horn off and found out that it is the L horn. Also note that the front color is almost a hunter green, while the back appears to be cadmium plated? So, the horn I purchased is the H horn, so I now have a matching set. I am in the process of cleaning it up. I've taken the horn apart, cleaned the face and back as well as removed the pitting from the bracket. I have the front face and bracket primed. I am now in the process of making a paper gasket. One last question, my horn has a Date Code of Y8, the horn I purchased has a Date code of Y7. I've tried to search and find a place that talks about the parts date codes for Datsun. Can someone point me to it or enlighten me on how to decipher them? Thanks!

@siteunseen - No worries. I was able to locate 1 horn. I am in the process of cleaning it up as it was quite rusty. Still not sure if it is H or L or what I have. It will work itself out in the end.

They aren't for sale, I was joking around...

Those look good to me, I'll take them! ;-)

I found an ebay auction for a 77/78 version and the H and L are painted on the bracket. I'll pull the bracket on mine to see if it is there. I don't see anything on the horn itself.

That is it exactly! I just wanted to make sure I wasn't missing something.

Ok, here goes. The first picture is the passenger side horn. The second and third picture is of the air horn. Upon closer examination, it looks like the OO removed the horn bracket, but reattached the bolts. So, I think I just need to figure out which horn tone I have and get the opposite. Wiring appears to be there also, just taped together.

@ramsesosirus - Thank you for the pictures. That helps a lot. You are correct, I was trying to explain that the brackets and mounting locations changed for the 77 and 78 model year. I am also trying to figure out which side is High note and which is Low as I can't find the painted H or L on mine. @Zed Head - I should have (and will) take a picture of the drivers side that has the air horn, my bad. I was trying to deduce what modifications if any the OO made in order to fit the air horn. I'll go take a picture and post it here.

Hi @Zed Head Per your advice, I reviewed the FSM, specifically pg BE-59. The picture is only of one side and does not really show how it is mounted. I also reviewed the diagram on pg BE-61, but it only refers to Right and Left and not High and Low. Is there a better page I can refer too? Any chance someone can help me out with a picture? Thank you!

Howdy Folks, The original owner of my 280Z decided to replace the drivers side horn with a Sears brand air horn. While I don't mind how loud it is I would like to remount an original horn in that location. I am thinking that the mounting of the drivers side horn is the same as the one one the passengers side? (i.e. it uses a bracket with a bend). I know they changed the style of mounting brackets for the 77 / 78 model years such that they are straight without a bend. If someone could please post a picture here, that would be great. Also, I am trying to determine which was the High and which was the Low? Thanks! ~Matt

So, I took the Z for a good ride today. The weather was fantastic up here in NH for late October. The car really behaved itself. No more hanging high idle. It was a real pleasure. Thanks again to everyone for their input. Cheers! ~Matt

That is a great idea! Thank you.

Hi Capt, Mine had the spring, the one I purchased did not. Mine was completely frozen because of all the coking surrounding the adjuster screw. There is a hole which reveals some of the coils of the altitude adjuster that I sprayed PB Blaster into, but it never freed it up. I was having the crazy RPM hang at high idle. It made life difficult driving in a parking lot at slow speeds and coming to a stop. I would keep the car in gear until the last possible minute and then go to neutral. Making sure I was below 10 mph. Thank you for the description of what it does. I had a rudimentary understanding of its function, but that does clear up some of the mystery of this troublesome device. As I mentioned it isn't one hundred percent fixed but it is so much more drive-able now and behaves way better.
