Now I'm not saying everyone should DIY it and not go to Al and Miles at AM Auto, but the info is there if you want it. I'm still tossing up whether to DIY it or send it to AM auto.\
From what I understand, it's basically crimping wires together that correspond with what they do (e.g. find the A/C switch on your car, then crimp it onto the A/C wire on the WRX ECU)
