Thread: Name that wire!

if the wire is green with black trace? cant quite see properly in photo. that colour was used for fuel gauge sender.

my only thoughts on the termination are that the winding is 'some' kind of variable resistance to earth indicating it fed a gauge

I can't seem to find anything like this on a wiring diagram and it does not look original anyway.

Any clues to the function or location of where this should be returned to?

That device on the end is typical of the switch used in the door pillar for an interior light and could be also be used under the bonnet as a trouble light switch.
Another use for that switch is for a tamper contact for an alarm, again could be found under the bonnet.

I got some more time to play and the wire originates from a supply on the heater control (not sure if it is switched or not). It then goes through a red light on the dash panel before heading of and terminating in the springy thingy.

Conveniently the red light is not marked. So could be choke, hand brake - maybe a crude attempt at indicating 4x4. I might just connect it to the brake shuttle valve if I ever get that going.

Odds on it is the Hand Brake on warning light switch (come to pieces).

Thanks toad, that would be a likely use for that switch, Mathernet did say ' I followed a green wire that departed the loom close to the clutch master cylinder and seemed to disappear over the fuel tank on the drivers side. '

Is his hand brake still in the original spot? have a look around for the bracket the switch parts fit into.
