Does the car run and drive?

I answered your post on the manual swap wiring thread as well. Should be all the answers you need there.

Hopefully previous owner didn't do too much hackery.

 

Yes it definitely does run and drive. I think I might do some tweaks to my atemu but all of this is for the sake of getting rid of all my cel codes

 

Yeah. I used resistors to get rid of my codes.
Maybe Qantum Auto has another way of doing it.
Atemu doesn't get rid of codes.
And you can fairly easily wire your car in a way that can do what the ATEMU does but that doesn't even need an ATEMU.

 

I have my resistors wired to sln+ and - slt+ and - and also slu + and -. I'm just now figuring this out after wiring my Atemu up.
