Was thinking on buyin an Apex VAFC VTEC controller for my 5th gen lude and was wondering when u buy it how do u install it is there a harness because my friend bought a used one and it had a harness but he had to cut the wires and hook them soder them individualy and which one is better version one or two?

 

i dont know personally about any harness. mine is soldered directly to the ECU.
