Default Need wiring help, newb here

Im taking the engine harness out of a 99 SS that I recently totaled, and going to be swapping the whole set up into a FD RX7.

Ive got the entire car broken down, I just can't seem to find any thread or write up on what Im supposed to keep.

Do I keep any of the interior wiring?

Do I keep ALL of the engine bay wiring?

If anyone has a write up or could help me out it would be greatly appreciated.

You don`t need all of the interior harness, just the OBDII plug. You only need the engine harness.

It's nice to grab about a foot of the interior harness after C220 & C230.

Call me an idiot, but the "engine harness" is only the harness that connects to the PCM and the motor?

I can disconnect the three connectors running along the passenger side fender and do not need these?

Thank you again

Some easy clues about the harness are the two large connectors that are attached to a large aluminum box.(this is the computer or pcm) Also the fuel injector connectors are on this harness. The relay and fuse boxes are also included. Hope this helps.
