so i have my swap but im wondering what a few things are on my harness. i just wanna know if its needed or not.

this is connected to the air tube coming from the back of the intake manifold

this is further down the harness and connected to a little plate, has JECS japan on the side of it

i also have the engine fuse panel and this is connected to it, says JECS japan on it
