MGB: can't find my wiring diagram

I was looking on this site (where I've seen the forums send other people) http://www.spridget-tech.com/page2.html and was looking for my car 1976 ser # GAN6UG175921G, but don't see it anywhere on that site. Am I missing something? I am going to be trying to fix the tachometer and when I looked under the dash, one terminal had nothing on it except a male spade end, and a loose wire, but with no end on it. So I figure the wiring diagram would help.

Thanks!

Near the very bottom of the list is a link for GAN5 through end of production in 1977.

I'm sorry, mean tto reply to this last week. Thank you for posting that link! Now, what the hell does all that mean? lol. I have no idea how to read this, and there's no legend on the page. How do I know which wire goes to my tachometer? How do I know which thing on there is my tach anyway?

Near the bottom of the page of diagrams is a link to "key for above". When you click on it, you get this: http://www.spridget-tech.com/wiring_diagrams/midget_mk_3_us-5.pdf

you were kind enough to link me directly to the diagram I needed so I didn't revisit the main web page with all the diagrams. Thank you again! Looks like when you're in Ohio next, I owe you a beer or two :)

I did this a few days ago. It's not the best, but might help. I can PM it or something.
