GM recommends just a single splice in those wires (per wire), so at the broken spot you could re-join the wires at that spot, or if that makes it too short, you can replace either side of that circuit with a new wire/appropriate crimped connector that is slightly longer, then join them, or you can replace the whole wire, with the right crimped connectors on each end.

And for the impact sensors, you MUST make sure the wires remain twisted around each other for the sensors to work properly.

charm.li will have wiring diagrams and a bunch of info on how to repair wires. There's also a bazillion youtube videos on it.

 

The break in the wire is somewhere in the larger harness the wires go into. No continuity on the one wire. So I think i need to replace both wires with a new sensor plug. Where can i get the wire and plug? Thanks
