Did mine six years ago (may have been the first possibly). Never had an issue since and because I changed the connector on the back to an ATX one, I can run several wires to the clocks. Best, most cost effective solution once its all working. Just retrace every line and if theres a blunder, you'll find it.

Make sure that it is fitted the correct way round otherwise it will not regulate!

Markings uppermost - no.1 (left) 12v in, no.2 (middle) ground, no.3 (right) 10v out. Ideally they should have a heatsink.

Here's where I mounted mine. Easy to get to it and just have to unscrew the little screws and pop a new one in if needed..wires from top to bottom are:
2 black wires are +10v (copper tracks bridged on rear of board)
3rd red wire is ground
Bottom red wire is +12v from ignition.

Well after 6 tries, finally given up the ghost.

MidLifeCrisis I take my hat off to you (he made one for me)

Will go back and try again in a few months just for my piece of mind, which is shot.

and found this on a german forum. Also for late:

E D I T: I repositioned the pin decoding list on my first pic and the second german one is for a petrol as it has no glow plug LED

Your tracing appears incorrect for Diesel, haven't checked it all but the Glow plug LED circuit from Pin 14 is incorrect - worth rechecking.

The picture from a German forum is for petrol vans as pin 14 (glow plug LED circuit and components) is missing.

Yes you right the second one is for a petrol as it has no glow plug LED

But the pin14 is glow plug/OXS/catalyc converter malfunction sign. Here is a photo of an original blue foil pinout:

The tracing from pin 14 is very pale, looking again in magnified view I can see it connects to the glow plug led so ok ...... :ok

afaik we didn't get the o sensor failure wiring on UK vehicles certainly my 1990 Syncro with the MV engine didn't have it the blue foil was was the same as that fitted to the year befores DJ engine van and the track isn't populated though it was labelled as shown and no led fitted in the holder and the cover for the leds had the blank in

It may only have been used on US vehicles, or for other early adopter emissions strict countries like Switzerland

Use 68K resistor for your Blue LED(sounds alot) but results in just the correct brightness.
