Thank you Joeyinal,
I already managed to figure out the purpose of all cables. :)
Orange brown turned to be for a digital clock option or something like that.
Best regards,

i got to figure out what to do with my exhaust on my 79. Thanks Daniel for the mention of Ram Air Restorations. I got look into something. My exhaust is barely hanging on and its on its 3rd time being redone. my original was destroyed removing rear leaf springs back in mid 90's.

First attempt I had a flowmaster system on it that had a 3" dual in and dual out transverse muffler but made for headers. I only had stock manifolds so exhaust shop made some custom pipes to connect. then I couldnt pass emissions with out a converter tried to get 2 welded in but could not get the fitment. it was way too big and i needed converters.

2nd attempt i went with the full system from classic industries..worst mistake ever. exhaust shop had to bend and heat everything and it costed more than it was worth. it held up for a good 8 years but now its not hanging right and I had to cut out half the system after mufflers.

If anyone has pictures of running straight off mufflers with turn downs . please share I need to figure how to get my exhaust supported at that point

Hey all I am picking up my new 77 TA Saturday and I have used this site to find out a ton... And I mean a TON of info on these great cars. 

  But I have a question and it may sound foolish.  I have used the search buttin and even searched the web but have not got a answer that I trust.

   L72 the L79 and L80  and the Y**  and all the other modle designations whare can I find a break down of what each mean?

  Thanks for the help I am sure this is an easy question for someone here.

i changed my gaskets to aluminum hoping it was exhaust with no help. 

my tick would somewhat come and go to, at times i thought it was gone, but others it was obvious. 
DriveTrain / Engine numbers & D or Round Port Exhaust?
« Last post by JD78 on October 29, 2014, 06:25:10 AM »
What's the best way to tell if D or Round port exhaust (without having to undo) & if engine is a SD or not.

Engine numbers are: C150911YC  &  21P321676

On the right exhaust manifold I think there is a CM3 code.

I also have the Ultimate X-over system, with Spintech mufflers. Don't expect it to be a bolt-on, there is a lot of cutting, welding and testfitting involved. I have the burnmarks to prove it :-D
The real issue I had was that one of the downpipes wasn't bent enough, so I had to cut out a slice, bend the pipe and weld it shut.
Here's how my car sounds with it: Trans Am sound clip:

Daniel, thank you!  I will look into Ram Air. Did you do the installation yourself? If so, did you have any issues with the fit?

Pretty sure the light and dark blue is for the rear speakers on one side. And orange brown i think is the cigarette lighter. Will check my wiring diagram tomorow
