i bought a front clip last week (start up before i brought it home) and did the swap this weekend. everything is in and hook up. the only thing that didn't hook up was a male blue plug next to the ecu. the sized was different and im not sure what that plug was. any way, the engine crank but it's not starting. i was wondering if i have to do any wiring or any difference between JDM and USDM. if any one have any ideas or comment, im appreciated. thanks.
