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.
b3 like mk2... fan sensor on rad... o 4 pn req... that coolent gauge and comp temp sensor....
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.
