I just want to make sure that these are hooked up correctly so i dont have to deal with them later. I had a few SR's in the past and i went off of want i knew about them.

1stIm hooking up the wastegate to a nipple on my hotpipe

2ndThe canister in the back for the butterflies is connected to the small nipple above the brake booster one

3rdfuel pressure regulator is connected to the small nipple on the TB

4thBOV is connected to the large nipple on the intake manifole next to the TB.

I think thats it, any problems with this set up?

the nipple by the PCV valve/brake booster line goes to the FPR. The FPR has to see vac and boost. The one on the the throttle body only sees boost I believe.

You are correct. The fpr and butterfly control get T'ed together and run to the same vacuum source. The vacuum line underneath the throttle body should be capped off.
