I'm not using the old cruise control I'm just plugging into the wiring. I found the mail side plug for I don't have to cut that one off. The four wires I need are in that plug.
Male side of under hood cruise control plug. $18.00 for all parts.

Just pick a set of Delphi 12613412 50lb @ 58psi injectors. I was going to run the 36lb flex fuel injectors that came with the p-59 But these Delphi 50lb injectors were too good of a deal to pass up. I picked up the whole intake with injectors and fuel rail at my local U pull it for just under a hundred bucks. It came from a 2020 Express 2500 the intake of the square port so I sell that on EBay and make some money back. Make it an even better deal for the injectors.

That's what I did to my purge valve set up. I wanted that hose set up on yours but couldn't find it and didn't want to wait on it.
I decided to use the LS6 Corvette Cam because it has less torque but excellent top end. With my blazer being such a short wheelbase some loss of torque would not really matter. That's why I wanted the trailblazer SS intake to help with the top end. Hoping to get everything done and running by March or April next year because I really want to do Rocky mountain race week. Not trying to win anything, just going to have some fun but I don't want to be the turtle at the track either.
I decided to go with a LQ9 cam so I would not loose the bottom-end torque but gain some hp. My objective is more of a daily driver. I picked up this cam from a guy on market place.He had bought a new LQ9 and upgraded to an after market cam. So the cam was basically just a breakin hrs cam. It came with lifters seals all for $20 plus shipping.
