i posted the elise plug.
you need one wire from the temp sender
one wire from gauge to earth
and one to a switched +ve so it powers off the key.
ive got an oil temp gauge i never fitted if you want it. £15 and ill post it too
though the mod to use the external temp readout would be pretty cool. just need to find out what resistance you need for the dash display and the pin that it connects to on the plug on the back of the display... no wait you could just hijack the external temp sensor wires!
edde i was looking for some info this morning re. dash temp display. have u got the details for the pins on the back of the plug for the display please fella? sure u have post6ed them before but the search sucks atm.
