modified cam sensor

[colin turner]

hi just tried to replace a faulty cam sensor on my 1996 1.8 vectra and found the replacement has 4 wires thet are to be spliced in the wiring loom. the original or faulty sensor has only 3 wires which i can marry up with the new one but that still leaves a black wire that i have no idea where it should go vaux dealer says its a modification but are less than helpful even though i got the part from them.maybe they want the extra cash from the labour any help would be much appreciated cos i havent taken old one out yet incase i run into big problems TIA colin

wire has got a plug that fits onto sensor on one end and other end has wires stripped.old plug not compatible with new sensor so i have to join/splice wires from new lead into wire loom but lead is about 14" long and only just reaches into loom protective cover behind rocker cover. could vaux dealer have sold me the wrong one?

the original connector has 3 wires and has wire shield around them. just strip back the wiring join the 3 colour coded wires then join the black wire to the shield wire. hey presto a very simple job.

sorry for being thick but i pressume that under the outer sleeve there is a wire mesh encasing the other three wires ie the shield wire?

You've got it. the mesh is the shield.
