LS-56-01 in an SE/TE

Are there any modifications I need to make to this stick so I can drop it in my SE or TE? I know you will need an MS mounting plate from what I’ve read but do I use the existing wiring harness in my TE or a different one?

Also, do I need to mess with the orientation of the stick (like turning the block to the right once) or am I good to just drop it in?

I am new to modding so my bad if this has been asked…I did search.

PCB has to be rotated so it is facing your left if you are looking at it (with existing harness)
