Hey all I bought the mkturbo full kit which comes with pretty much everything including ms3pnp pro and an mtxl wideband. These are my first steps and I am intimidated by the wiring. I finally got the stock ecu out and plugged in the ms, but I'm not sure of my vacuum line placement(pictured). Also was I supposed to wire in the IAT?
The wideband needs switched 12v power and a ground, people suggest to ground where the ecu is grounded... where is the ecu grounded? What wire should I use for power? Do I need to use the stock o2 sensor plug for anything or can I just disconnect it from the sensor and leave it?
If anyone has a 99-00 or similar car can you send pics of all wiring involved please? I know "hold my hand." Please explain like Im 5 because I am not a mechanic. Thank you for any help
