Hi anyone know what colour wire goes to what?
I have got a mk2 nb instrument cluster and the 22 tooth red gear sensor to use in place of the mk1 an cluster.
The sensor has 2 wires a blue/yellow and a blue/white one, the wiring diagram for the mk2 cluster shows orange and a yellow wire, the connectors that came with the cluster doesn't have the yellow wire that could go to the sensor, the only yellow wire joins a black/blue wire grounds for gauges oil,water temp, fuel.
I think L&M of the black connector are are the sensor one L is white/black and M is orange.
Not sure if that's correct and what way the sensor wires go, anyone have any ideas please.
Regards Mick.
