2008 will most likely use a T4 controller. It is what you should be putting back in there. T1 was used back ~2000(?) The T2 is the upgraded big brother and is often used when a T1 goes bad. A small wiring update is needed for the swap. The T2 was used 01~04. 2005 cars used a T3 controller and was only used for that year. ---

> You can use T4 or T5. Noted. I just didn’t want him trying to go backwards (if that was his idea). ---

Yeah, a t2 wont run a t4 car. But a t5 is suppose to be backwards compatible. ---
