No.? It is simple and straightforward.? Like I said, remove Negative from battery.? Hook up jumper from Positive to removed ground wire at Negative like I spoke of.? Electricity will effortlessly drain out of capacitors in ECU; I spoke of overnight, and this is probably not necessary, heck just go buy a pizza or something; but in my experience your really want old memory to be totally deleted.? The ECU's mind will now be back to factory settings. But really....keep the Red Wire on Positive Terminal.? Disconnect the Black Wire on Negative Terminal, typically a 10 mm wrench.? Little wire from Positive to removed Ground; it probably only takes a few seconds.....but, what the heck, capacitors are a little mysterious.....so draining them overnight is not a bad idea.
