Almost fix ended

[INTERPRO]

Good morning,

I want to thank everyone that helped me troubleshoot on my last thread. Cleaning the fuses fixed most of my problems with the engine codes.

I have 3 codes left on my (brake, cluster, and body controller, please check [jpro codes image]). I found some things while i was checking my body controller as follows. I already cleaned the corrosion on P1 and P2, but I still have those codes left.

P1. Corrosion on some plugs
P2. Corrosion on some connectors
P3. 2 connectors that looked like they belong together they were disconnected. (check images [green-green disconnected.)
P4. J2, J4, and J5 have errors on Diamond logic builder (check images [ESC J2, ESCJ4, and ESCJ5])

I have some questions on these problems
Q1. are those cables supposed to be connected or disconnected on problem P3
Q2. Is it normal to show red on P4?

This is the green and yellow cable that looks like it goes with the green and green cable inside the kick panel next to the Cab controller. Thanks for your input

Here is a better picture of those two plugs
