You need to get service manuals for this. Every new question you seem to come up with is in the wiring diagrams/pinouts/component locators. I don't know how anybody would be able to do a swap into a custom whatever without service info, and probably a really smart person wouldn't even attempt such a thing.

probably I'm not so smart...........

bytheway I didn't do the swap I just bought the chassis with the swap already done by someone I don't know and I built my car over so even trying to understand where the engine and years came from was very difficult.......IMG_5342 (1).jpg
