What is this bare wire that is running in the same part of the wiring harness with the knock sensor? Is it supposed to be a ground?

 

It is a little hard from the picture,but things in that area besides the knock sensor is temp sensor,and further back is 02 sensor,can you follow it to where it connects?

 

Its just hanging there, not hooked to anything. There are 2 wires going to the knock sensor, 3 to the oxygen sensor, and 2 to the temp sensor which are the ones that are extended in the pic where I relocated the temp sensor for the 97' engine. This one is bare and runs along with the 2 wires for the knock sensor.

 

is this the original motor?

 

No this is a 88' with a 97' engine. That is the original wiring harness. I noticed the wire when I pulled the motor.

 

Anybody??

 

If its in the harness but not hooked up on either end then just pull it out! That is if the truck runs fine!?!?

 

I don't know where the other end is and it runs ok except for starting. Kinda sputters for 2 or 3 seconds then smooths out.

 

The spuddering is probably just ur O2 adjusting! Follow the wire back & see where is runs! Have u tested to see if its live???

 

No this wire is bare, has no insulation. Is it a ground? Does anybody else has a wire like this running together with the knock sensor wires?
