I bought an AP1 2001 Engine wiring harness.
I like to identify 4 connections.

1. Black w/ red stripe (one wire) oil sensor?
2. Red w/ black stripe (one wire) look like coolant temp?
3. Inside sensor is white but broken (look like ceramic)
4. Two wires - yellow and the other is black
Near the injector.

Thank you

so much

 

1 is ac compressor
2 is a knock sensor
3 is starter
4 is cam sensor

this is just me giving it a wild shot from memory.

 

RIGHT ON!!!
I appreciate very much.

 

ah and a good old broken knock sensor still plugged into the harness even

 

oh, I forgot one more plug with broken wire.
Green and Red
What plug is this?

 

I think I am wrong looking at that first picture again... 3 isnt for the starter. the one between 3 and 2 is. I believe that is coolant temp sensor plug. does it have a white line on the red wire? then its temp.
For the new one you posted I believe that is cam sensor 1 or sensor A and the one that was cut off number 4 is cam sensor 2 or B.
1 or A should be red and green wires no stripe, Goes on intake manifold side of the valve cover.
2 or B should be yellow and black wires no stripe. Goes on the top of the valve cover.

The #3 has RED with a white stripe and GREEN with a yellow stripe.
I extracted the white broken sensor shown beside the connector plug.

 

Yep, then number 3 was coolant temp sensor.

 

Thank you, JBamin - I owe you a lunch.
