    disconnect the negative at the battery...

    pump the brakes a few times to gt rid of any charge...

    remove the battery fuse, and backup fuse. 15, 7.5

    everything back together and ecu reset?
    Got an old Videogame console, handheld, games and accessories. PM me! I want them

    Im pretty sure just disconnecting the negative terminal on the battery, resets the ecu too. because it cuts power off to everything.. unless the fuse box holds a charge...

    well I know mine works because I did it last week and it def the safest way to do it.
    + its good to reset the ECU whenever you change engine/performance stuff this way the engine gets a chance to adapt to the mods you made and run at its max
