04 zx3 injector wiring busbar

Hello everyone,
Im new to this forum but i need some help. Im putting the original 2.0L dohc zetec motor back in my focus. I put on the svt intake manifold, fuel rail and header downpipe. Im having trouble finding where all the wire connectors go, coming from the original zx3 injector wiring busbar. I have 3 connectors i cant figure out. 1. Is 1 wire, black with orange stripe. 2. Is 2 wires white with black stripe and brown with yellow stripe. 3. Is 2 wires brown with white stripe and white with violet stripe. When i look them up i cant find anything about 1. 2 says knock sensor and 3 says camshaft position sensor. If anyone knows anything about wiring and can help me out that would be great, thanks.

Oil Pressure Switch.
It's near the oil filter, just above and to the drivers side. Get it from underneath.

Sounds like the Cylinder Head Temperature Sensor.
It's just below the intake manifold and has a ~6" pigtail with a connector on it. PITA to reach from the top. From underneath is a little easier and you can see it.

Knock Sensor is my guess. When you're underneath it'll be the last connector hanging vacant.


If the 3 are all coming out the passenger side of the FI wiring, I should be correct. They should be coming out there. The only ones coming out the drivers side are for IAC and TPS.
