Since I listened to internet people, I need to cut a access hole to allow the trans plug to fit here.
This is from under the car, the connector needs to be able to have a harness plug into it.
So, my idea is to cut a square out from the inside, see dashed lines below
Then weld a plate over the inside with a grommet riveted to it, similar to below
Thoughts? I am not a welding/body etc kinda persons so wanna get some opinions before I cut away. The hole was from a pilot drill, was gonna try a hole saw, but that was not a good plan. Measured out decent though, found it first pilot hole/
