VDO Gauges

[Sean Conway <Sean_Conway.PANDP@PANDP.co.uk>]

OK, here's a cry for help to all you guys who have fitted VDO gauges to your 
cars.

I've bought a set of second hand gauges from a VW breakers (unfortunately 
without the senders). They've come out of an Audi and are fitted in a panel 
which is exactly the same as that which you can see on Ryans page. I want to 
fit them in the ashtray aperture and have bought a Zender instrument panel to 
carry the gauges. This is designed to go in the radio aperture but as the holes 
are the same size,  it will do the job.

My car doesn't have a gauge fitted next to the ashtray, just a blanking plate. 
So here's
question one.

How much do I need to cut away (ie the divider between the ashtray and the 
gauge hole) in order to make these gauges fit. Do I need to cut out the back of 
the ashtray housing to feed the wires through ? What's the best way to fix the 
new panel (which has no fixings itself) ? OK so that's three questions !

Question two concerns the senders for the guages. My engine is a non-injected 
1800 EX with hydraulic tappets (is this a term you US boys use ?). Consequently 
I don't have any of the sensors fitted as standard which will drive the gauges. 
Genuine VDO senders are mighty expensive - have I any other options ? 

Just for more info, the gauges I have are a voltmeter, oil temp (170 degrees C) 
and an oil pressure gauge (5 bar). The voltmeter doesn't need a sender, and I 
seem to have a blanking plug on top of the oil filter housing which will take 
an oil temp sensor. My main problem is the pressure sender. My existing one 
will just drive the buzzer, but I don't know where the best place is to site 
the sender and I don't know if senders are interchangeable etc etc. 

Any advice is gratefully received !
