Bagged compressor wiring, why so hot?

Hey all, the rear bag kit is in, everything is wired and I am able to operate the system. This is an Accuair e-level setup with an Air Zenith compressor. The hot wire coming straight from the battery to the relay is getting very hot when the compressor is running. Is there something I'm missing on how wiring works?

Currently I have a 8awg from the battery to a 40amp fuse. 8awg to the relay. I did confirm the battery goes into the "30" pin on the relay and the compressor is on the "87" pin. There also seems to be a small wire going to the e-level controller that is attached to that 8AWG battery wire. It does not seem to get hot even though its on the same line.



The wire I'm holding is the one to the battery. Also the one getting so hot that smoke is coming from it after a little while of the compressor running. Almost like there is a major amount of resistance at that wire. The wire is not hot at all at the battery end, only at the relay end.

Relay is
87 --/ -- 30
86----85



Last image I have is the wiring diagram I think is correct? So looking at that the wiring seems to be all in the right place.



finally, I did start with a 70amp inline fuse and dialed it back to a 40 amp since I only have one compressor and thought maybe I'm allowing too much power through to the relay. It doesn't seem to have fixed the issue.
