I have a temp gauge that's not working on my 1989 2.8 4JB1 Bighorn, can anyone tell me

A. which one is the temp sender?
B. what do the other 4 or so senders in and around the thermostat housing do?

The large one on the top with two wires coming from it on mine has snapped both wires off.
I deduced that was the cause of the non working temp gauge but upon ordering a replacement I found it was a different sender than the two wire one.
Any help would be great.

Cheers

Alex

I have a whole broken 2.8 Bighorn in the shed, come have a look... the sender was working fine when it blew up

Cheers Steve, I got your map to the shed so will give you a call, in the meantime I have discovered which one is the temp sender after a very dodgy attempt to reattach the wires to the sender I thought it was only to find it was another one.

Now my question is what does the sender in the photo that follows with the Smurf shit on the top do?
