Quite easy my friend!
10) Cut the WHITE/RED wire on ECU pin 65. (Leave enough wire on both side so that you can reconnect to both sides)
11) Connect the Piggy Back’s GREEN wire to the side of the cut wire that leads away from the ECU.
12) Connect the Piggy Back’s VIOLET wire to the side of the cut wire that leads to the ECU.
That Red/White you cut...
Take the piggy's green wire and solder it to the end leading into the car. (Under your dash)
The other end of that Red/White cable...
Take the piggy's violet wire you cut and solder that wire to the end that is leading back to the harness(Not the thing you unplugged it from but the thing doing the plugging) The gray piece
Nothing major will happen if you get em reversed. Your car will get bad gas mileage and stutter.
