SBC starter wiring issues.

Okay so I am electrically retarded first off, I have spent the last several nights researching and tapping a few wires jamming myself into small places with a multimeter and a prayer and am down to just hoping someone can help Because the fsm's make no real sense to me.

I am trying to wire everything to start, my battery is in the passenger bin, I have run a wire from the battery to the main stud on the starter, to my FC alternator rear stud where the brown standoff used to be, then to my engine fuse block, from the fuse block i have a ground strap running out of the other side of the main fuse to the body.
Picture for reference. The side closest to me in the picture Has the ground other side has positive lead from alternator.

Currently my ignition switch is connected to what I believe is connector FE-05 on the black wire with white stripe I have my ignition switch taken apart I tried tapping into the red and black wire on it but had no result when I turned the key no nothing. My current results are not any better.
Picture for refernce.

Any help would be greatly appreciated this issue a drive shaft and my radiator hoses are all that are keeping this thing from being derivable.

The black wire with white stripe is indeed the ignition wire.

Not sure what you did with your wires in the picture, I just cut off the end that went to the RX7 starter and put on a new end for the Chevy starter and it works no problem...

If I am reading this right it looks like you possibly grounded your main chassis power wire? That black wire on the other side of your primary battery feed to the fuse block is indeed what feeds the rest of the car. Color misleading yes. You need to find its mate that has a simple black clip connector and plug it in. Obviously test this with a multimeter before actually doing so. But I think that is your main problem...

I sent you a PM a little bit ago but just saw you posted this.

Looking at your pictures i'm actually a little worried about your potential for an electrical short and fire...

I agree with 86svo9l, you should be able to simply use the original wire going to the factory starter solenoid. That also goes for the main power lead to the starter, which should be going through a fuse first if I read the FSM drawing correctly. If it's too short for the new starter location, you will want to replace that wire with a longer one instead of splicing them.

I would suggest that you put back all the splices you have done and put it back to stock before moving further. Otherwise you may be chasing an issue with what you've tried so far.

Yeah I got it sorted, sorry I haven't replied dealing with all the little gremlins. And wiring was cleaned up in a big way just was looking like that while I figured out what the hell was going on.
