Passenger side firewall next to AFE intake I have a solenoid with a green and yellow wire to it, it has a vacuum line (I think) to it and a exhaust muffler. Can someone tell me what it is and what function it performs.

Sounds very much like an exhaust brake. Jacobs e-Brakes have the solenoid mounted on the firewall near the AFE. The wiring scheme sounds like Jacobs. PM me with your e-mail address and I can send you a PDF of the Jacobs e-brake installation directions, and you can check for the rest of the hardware, how to operate the system, etc.

previous owner/s must have removed the exhaust valve because its not where it should be, oh well will just have to be extra careful with a big load in the mountains (unlikely for me) besides I have a six speed. Plan ahead!

Well...check around and see if you can get an e-brake installed. It can be very nice to have ....especially if you have a big load...especially if you are in the mountains. I too have a six speed....but the decel/braking from basic engine braking is nearly worthless....
