The engine harness by the injectors, it has a grey think cord, which has a thin black one inside, i think its a sensor wire or something, but its like...

Grey plastic
Silver wire
Black plastic
Silver wire

Do the silver wires send separate signals, or is the outside wires just insulation or something from other frequencies?

if anyone knows i would appreciate the info thank you.

thanks Samuel...i was hoping cause i just wired that one...

also theres two black ones, and two black with white stripes...does it matter which one goes to which one?

thank u

 

The O2 sensor uses a shielded cable, so make certain with the rewire that shielded part in no way makes contact with the inner wire or the signal will be grounded.

 

well now you are aware...

The O2 wire is shielded, and is a black wire inside a grey plastic tube at one point

 

Shield Jacket is white, but looks grey after 10,000 miles
