I'm pretty much done with the engine swap to a 350 TBI (from 305) and we got everything put back together except for a few little things like the AIR system. It's a brand new Ultima Red top and it's putting out 12.59 volts from my multi meter. It's grounded and I checked that already. I then checked all my fuses, all good there. I have the avital avistart 6500 and it has a starter kill so I put that up to the battery like it was before and it worked fine since it's it's own brain so to speak. Even the remote start tried to work but engine didn't turn over for some reason. NON of the interior lights work, not even the headlamps come on. Nothing works, no windows, not even the power hatch so that's stuck up, I need help. I looked around and everything is plugged in except for the WOT sensor on the new TB and the "brown" wire for the distrib. I'm going to reconnect that if that has anything to do with it but I highly doubt it. The 91-92 air split isn't plugged in either, it's a nasty device that has two plugs going into the AIR plumbing then splits out to either side of the engine. I don't think that is it.
I'm starting to think that I have something wrong with the distribution block and/or the starter hook up. One of my dumb friends went under the car (shouldn't have let him) and took off the starter/solinoid wires without remembering where they went. Then he messed with the distribution block (positive).
Obviously it has something to do with the wires under the hood. I'm just trying to find a diagram that tells me where the wires go, I thought we did it right and yes the car is grounded.

I've never seen the wiring on your car but GM tends to do the following:

The purple wire goes to the S terminal on the starter (it's the cranking power) and everything else goes to the battery terminal on the starter. The R terminial is likely unused.

 

perhaps the bulkhead connector has been pulled losse at the drivers side fire wall.

just throwing out a guess
