Could someone tell me the process of hooking up an ECU?
Hey everyone,
I just bought an M2 Stage III ECU from a fellow board member. This is supposed to arrive Thursday, but I won't be able to get to it until Friday. I need to have it in by Friday night because I am going to the Banzai BBQ on Saturday. Could someone please tell me what I have to do to swap out the stock ECU and put this one in? Is it just unplugging and replugging or is there more to it than that?

*Pull up scuff plate, it just has two snaps.
*Pop out the two plastic clips for the passenger side kick panel and remove panel.
*Undo a few screws holding the stock ecu and carefully unplug wiring harnesses from the "front" of the ecu.
*reverse instructions for the new ecu
Just be careful with the wiring harnesses and make sure that you don't disconnect the grounds. It's really easy.

I forgot, you won't have to mess with the ground wires for the M2/Pettit ecus (standalone only). Don't worry about it. And I forgot something important -- FIRST STEP: DISCONNECT THE BATTERY!
