I was replacing camshaft position sensors of the M278 engine in my E550. Since I broke some of the sockets while unplugging them (given the cold weather), I ordered new plugs together to replace them as well. So far so good, successfully replaced all camshaft position sensors and the plugs, then forgot to take a photo of the leftmost side one. Unfortuately that had different wire colors (all brownish; may be due to color deterioration from its age) from others (red, light brown, dark brown). Can anyone tell me the order of the left most (when you look toward the car engine from the grill) camshaft position sensor plug wires, or share a photo of them?
Thanks!

When seeing that connector called Hisrchmann Sealstar 1.2, 3 pins or 2 pins, use camera and zoom their pin numbers. Observe the flat or curve side.
