Hey Guys and Gals,

Ok, finally found that almost 9 times out of 10 if you get the service engine soon light on after your HU install it is most likely caused because of the A/C control unit. You disconnect it when you install the HU and if you test your HU without connecting the controls again you install will register a fault even if you connect the controls later on, it wont matter you will still need to reset the light.

Hope this helps you guys out!
