So MY16 CPMB, but what are the wire colors going to the plugs? One's a two-pin, one's a three-pin, but the only way to confirm what they should be plugged into is to know the wire colors on them to which pin position so it can be determined from the wiring diagrams document which specific plugs they are.
The three-pin looks like it might be the G28 engine speed sensor, or the G31 charge air pressure sensor. But I can't see it being long enough to reach to the G31 (on the intake path hard pipe in front of the ABS unit). It's near where the G28 would be, but why is it disconnected? The two-pin might be a fuel injector plug. Again, the critically necessary piece of information, the wire colors and pin positions, is not clear enough from that video to confirm anything.
If you mean on the 2-pin:
pin 1 - red with yellow stripe
pin 2 - brown with green stripe
then that's the plug for injector cyl 4 (rearward cyl)
As for the 3-pin, can't resolve anything from that; which color is on which pin? And why does the video seem to show at least one of the wires as striped, and one appears to have yellow.
green/red on 1, blue/gray on 2, black on 3 would be the cam position sensor, but that plug is too far down for that. Still thinking it's the crank position sensor (aka engine speed sensor) there on the block near the bell housing.
4-pin in the back, going to guess it's the post-cat O2 jump sensor. Hmm, wire colors for 1 and 2 and 4 are right, but the wiring diagrams show 3 as being violet rather than black. Still, can't see it being anything else, so probably that. Normally that sits in a bracket mounted to the top of the bell housing, and the post-cat O2 cable plugs into that plug.
