So my starter wire burnt into, & the other wire that runs with it in the harness is a knock sensor wire I've found out. So I'm curious as to if anymore wires should be in that harness bundle & how hard it is to rewire a new knock sensor. I just buy a connector & wire it into the harness, correct?

The green/burntBlue wire is the knock sensor wire, correct?

 

Yes that’s the knock sensor wire - the starter solenoid wire is purple.

The only other wires that would be in the bundle are the wires for the front axle actuator, if it’s equipped with 4WD.
