98SupraNA

I have a 98 NA Supra. I want to know how do you add and tweak cruise control right after swapping to a TT motor. I know I need to add a TT cruise control actuator and cable, but where is the connector for it? is it part of the engine harness? then the question of the signal in between the CC button/function on the steering wheel to the ecu. Do I need to rewire anything? I don't know much about connections, but I have no idea where the ecu gets the CC input from the from the steering wheel, especially after a swap.

One last thing...how do you perform the 12 volt mod on our motors? is it really necessary or not?
