XJ12 temp gauge with pinto water temp sender

[ken]

Hi,

I liberated nice temperature and fuel gauges from a scrapped Jag XJ12. Any ideas how to hook up to temp gauge to the temperature sender.

I've experimented with a couple of configurations, but I either get no movement or the needle goes over to the far right.

Do I need to put in a resistor or something? Or can I get a sender which will "drive" this gauge correctly?

If it helps, the brass spade connector has at '+' symbol embossed on the plastic beside it.

I have (unscientifically) recorded the response from the pinto water temp sender. The results on a google chart are here.

This might help someone figure out how I should connect the gauge.
