the reason I said that is to accommodate the sensor that is there on the 1.6 but maybe that one isn't needed? Whats its purpose on the 1.6?

So the glowplugs on that flange enchance the interior heat?

Yes, they enhance interior heat by adding a minuscule amount of heat to the coolant, but more importantly robbing power.  By increasing the load on the engine it warms up faster.  If you don't mind taking 15 minutes for decent cabin heat, then leave them off.

lol, never thought about the added load to the engine, by way of the alternator..

The B4 Bentley is 2 huge books. It doesn't specifically cover the B3, but they are very similar. Since you are going mTDI, if you know your way around the IDIs the engine really isn't anything special. You could even get the MK3 Bentley covering the TDI. It would likely cost less than the Passat version.

This old WTB ad might be of some help

Essentialy the only things wiring wise I need to hook up to the tdi is the 4 pin coolant sensor for the fan, the alternator, stop solenoid and starter stuff? glowplugs optional.

computer temp sensor?
So all i really need there is a 2 pin for the temp guage?

Also do i have to take off the black cover on the alt to get to the w terminal?

is all the wiring for the injection system and other computer related crap pretty easy to remove? is it all bundled together pretty well? i saw that it had some sort of wiring harness running up under the back seat.

The crank position sensor gives 4 pulses per rev.  I've been planning on using a flip flop circuit to cut that signal in half and drive a gas tach.  That signal would already be correct for any 8 cylinder 4-stroke tach.

looks like this one would do the trick.
