VSS (Vehicle Speed Sensor) The Digifiz requires an electronic Vehicle Speed Sensor (VSS) for the speedometer display. This is fitted onto the gearbox in place of the mechanical speedometer cable. The Vehicle Speed Sensor that mounts onto the gearbox has three electrical terminals: +12V, ground, and speed signal output. For VSS wiring refer to the following CE1 or CE2 section as appropriate. 2a. CE1 VSS (Vehicle Speed Sensor) wiring TODO 2b. CE2 VSS (Vehicle Speed Sensor) wiring On a CE2 vehicle there is a standard method of wiring the Vehicle Speed Sensor to the fusebox, as was done on CE2 cars that had a VSS as standard such as the Corrado and certain Golf MK3s for example. The 'proper' way to wire your gearbox speed sensor is therefore to use three wires between the VSS in your engine bay, through the bulkhead and to your CE2 fusebox, connected in accordance to the table below. CE2 fusebox terminal Colour Function VSS connector terminal G1/4 Black Supply +12V to VSS 1 G1/11 White/blue Speed signal from VSS 2 G1/6 Brown Supply ground to VSS 3 The speedometer signal that goes into terminal G1/11 is routed inside the fusebox to fusebox terminal U1/11. Therefore, if you have a Digifiz loom that follows the CE2 charts above, your Digifiz should receive the speedometer signal at its WL7/7 terminal. BACKLOG LIST / TODO / NOTES ========================== - Use colour coding to distinguish between CE1 and CE2 everywhere, e.g. for entries in tables and paragraphs. Use black for information that's applicable to both. Proposed sections: - CE1 installation, CE2 installation - Odometer reprogramming (merge in from other old FAQ) - PCB version identification - Known faults and fixes - Basic power up test procedure - Full test procedure
Bringing this back from the dead. I have the equivelant wiring colors for MK1 CE1 if anyone is interested.
I've been meaning to update this with lots more info, including the actual factory pinout for the CE2 cars which is a bit different to what you would expect... I'll try to sort it at some point soon.
