Here's my throttle body before I put it in. I also had a hi temp coating put on it, hence the shiny black paint. 
For the power system I upgraded the stock 6 guage wires to translucent 4 guage, put side battery terminal adapters on the battery, and put on some very nice JL Audio battery terminal adapters. Heres the stock 6 ga grounding wires with that goofy GM connector next to my replacement 4 ga ground wires connected to the JL battery terminal.
