When doing an ls1 swap on an rx8, how do you get rid of the traction control, battery, and engine light staying on?

 

If you have to ask then you can't do an LS swap.

 

Maybe try looking at all the nonsense that's required just to do a basic swap in the first place, because there's lots of fun sensors and triggers and computer bits you've gotta make realllly happy before any of that ****'s gonna work.
