Hey guys, I'm doing an rb25det s13 swap and i was prepping all the engine and tranny harness wiring and i needed to know what these wires were and if they are even needed?

Well the first picture looks like part of the lower harness from the rb. As long as the connectors are there your good. When I did the swap on my s13 I reused the Ka lower harness and some wire mostly from the rb one.

I have no clue about the second one. Mine didn't have that black box but mine was cut there and I left it and have no problems, besides when I last drove it my windshield wipers randomly start working. But it never happened the 2 months I drove it until I last drove it. But I believe that mine is an unrelated issue.

For the main harness I sent mine off to jeff at jordan innovations and he did a great job.
