clutch: (can be wired either way round though, makes no odds) pin 1 - ign live pin 2 - ecu brake light switch, brake light half: 1 - perm live 4 - to brake lights and ecu cruise half: 2 - ign live 3 - ecu again these 2 groups can be wired either way round as just on/off switch. the important thing is to get the 2 wires for each half of the switch to the right pair of pins
I thought I was loosing the plot! Just when I thought I had learnt to read the diagrams I was thrown by the clutch wiring on here! I had the brake switch wired up ok tho, which is a relief! I tend to work out the wiring myself and then get confirmation from the Internet. So far so good!
Sorry to dig up an old thread, I'm currently wiring up my brake and clutch switch's in my mk1 jetta pd130, brake switch I've done fine, but clutch switch I'm having an issue with, is the clutch switch suppose to be naturally open? So when clutch is depressed it connects 12v to pin 66? I'm not using original mk4 switches, am using mk1 brake switches T'd inline on the clutch pipe.... Got vagcom connected and when power is applied to pin 66 I get the no 1 appear on the screen to show its working..... Just want to clarify that's all...... Or am I missing sumthing daft!
looking at the diagram I'm pretty sure its normally open, so opposite to the brake switch. I'd just get a MK4 switch for it anyway, plenty to be hgad from the scrappy. same goes for the brake switch since you need a 4 pin one anyway for full functionality.
