I had a fault of the car misfiring when hot. When investigating, whenever I grabbed the engine wiring harness the engine would misfire/stall. Fault codes of RPM sensor & knock sensor recorded. Then the engine would not start at all, I've now solved that by fitting a new crankshaft sensor, all good there. Tracing back the wiring from the knock sensor, after the standard 3 pin adapter, I can see a break just after the adapter in the wiring harness. It seems like it uses a shielded cable to presumably take the earth to the ecu. Does anyone have any experience of joining standard electrical wiring to a shielded cable? I've got a soldering iron at the ready but can't work this one out. It's a V6 CF2 by the way.
