hi all, i just bought a xj cherokee with 6" lift and 33" tyres, pretty cool 2 door.

The temp guage doesnt work? which sensor is the one for the guage, theres a big sensor that is in the welsh plug hole at thefront of the block, what is that one for?

i went to the auto shop, they showed me one that was pretty small, one wire attachment.

any help just locating the guage sensor would be a help.

Cheers, Mick

any idea what the sensor is on the lhs of the block under the headers in the 1st welsh plug hole? it has a sensor in the welsh plug but its not plugged in.
