Thanks for the link.
I'll have a poke around down there and see if it's fitted or blanked.

Hmmm......
Comparing the one on "the samba"



With mine...



It dosn't look like mine ever had a sender there, but it's a b suffix engine in a 1986 van, and has the yellow wire that someone has earthed.
I'm confussed dot com.

Unless someone stripped the thread and welded up the hole.

Is it possible your van has had a replacement (early) engine / crancases, therefore there is no location for the second pressure sensor ?

B suffix case is a late case, clean off the oil and it will be clear if it has been welded up.

other than the part number moulded in you can check this...
early late case by Paul_Barr, on Flickr

Mine's definately the wider casting which makes it a late engine.
I guess someone did weld up the hole.
Cheers guys.

worth checking it closer to see, if its a weak point it could fail

Great post. I know it's old now, but has anyone done this mod for a diesel? Is it a similar process?

My van came with the clock instead of a tachometer. Would be nice to put one of these aftermarket tachometers on the dashboard.

 Usually a signal is taken from one coil of the alternator on diesels.
You used to be able to get a sender on one injection pipe that worked by sensing the pulse and converting it into an electrical signal as well.

I checked my alternator last night and it does have the W terminal. Does that mean I can attach an aftermarket tachometer and get an rpm reading?

There is another wire going to the W terminal though, any idea if/what it will be using it for at the moment?

if it's a late van it should have 'buzzer of doom' oil pressure monitoring, that would require rev signal
if not maybe split charge for leisure battery set up

Interesting, it does indeed have the 'buzzer of doom'.
Can more than one device be connected to the W terminal? I.e. 'BOD' and tachometer?

yep that's how it is done in a factory rev counter set up, it's split on the foil board, once split the trace goes to the bod circuit and another trace goes to the rev counter
You could t into the wire before the 14 pin connector to supply your rev counter
You will need a rev counter that speaks w signal as opposed to the more common petrol ones that speak coil signal

Cheers Aidan, I've just ordered a Diesel aftermarket tachometer. It would have been nice to have a factory tachometer instead, but I suppose the big clock will have to stay.

Slaughterhouse offer a Tachometer that is a copy of the VW type fitted to the T25. It’s designed to use the standard Temperature and Fuel gauges unlike the VW Tacho which requires different shaped gauges. Fitting an after market Diesel Tacho requires it to be calibrated to suit the engine as the pulse frequency varies due to different rotational speed of the Alternator. More expensive than a standard aftermarket model.
