TV cable hookup

[landpro00]

I recently noticed that my TV cable is not hooked up on my truck, in fact apparently the shop that swapped out my TBI TO a Edelbrock Performer carb. removed it all together and didn't give it to me.

I would like to reinstall it so that my truck downshifts on acceleration like it's supposed to but I have no idea where to begin.

Where does the cable or whatever that controls it come from and can I purchase a replacement from my local auto parts store?

I ordered a bracket from Edelbrock (part # 8031) that is supposed to allow me to hook it up, but can't figure out how or where to mount it. Does anyone know?

I also noticed when trying to figure out how to mount above mentioned bracket that the throttle cable makes a big loop before going to the carb. Is this OK or do I need to shorten or buy a new cable?

Beginning to think the shop that did the work didn't know what the H**L they were doing. I've already had to take it back to them several times for other things and after the last visit I think I pissed them off so probably won't be going back. LOL!!!

Any help or advice would be greatly appreciated, THANKS!!!
