Stock boost solenoid (2 port) is OK, but a 3 port is much better.

Stock MAP sensor could be OK, depending on the boost you're running!

The knock sensor is a microphone and has two connections. The OEM wiring grounds one side at the sensor and runs just one wire back to the ECU, in a screened cable.

If using a twisted pair cable, run the pair back to the ECU and connect the signal to the original signal wire (in place of the original) and take the other side to an analogue ground at the ECU. Cable screen to chassis.

Thank you. I also ordered the 3 port boost controller from you. ;)

Not a lot left is stock on this car. I'm just trying to get these few bits wired on then Jamie can map it properly.
