Had a shop pull my chevy block for me.
The A.S.E mechanic pulled the engine, but did not disconnect
the knock sensor. The wires broke about 4" back from the connector.
Also, the wires leading right up to the connector have had the insulation
damaged.

Can I somehow check continuity running back to the PCM on the
send/return wires? I don't have the factory wiring schematics.


What is the best way to repair this. I definitely don't want to just
rig it back together and risk wiring issues in the future . I want to repair it the absolute best way possible.

Thanks!

If there is enough wire left just solder and shrink wrap a new section of wire to it. The mechanic is not required to fix it for you?

First, he who broke it, fixes it. Otherwise, there's no magic in these wires as a simple splice will do. Solder is best, but not required (there's little to NO solder used by the factory). 2 wires won't be a knock sensor as they use 1.

I don't trust his competency now.Not only because of the broken wire, but also several other things.

The insulation is damaged in four to five places over about a 6" run leading up
to the connector.

the component is a round flat donut shaped piece that bolts to the diver side of the block just under the head. The engine is a chevy 4.3 from a 1500 van.
