Default temp sensor

Getting tired of the gauge not working. Where is the temp sensor located on a 87 renix.. Its not in the thermo housing so where is it. Brother said side of block and I looked and can't find it.. so wheres it at? I want to see if its just a broken wire or whats going on. When starting it will cycle from cool to hot and back down then go back to 0 and stay there.

I have a 1990 4.0 and the water temp 'sender' is on the cylinder head, rear, drivers side with a wire going to it. Attached is a pic where the 'sender' screws into.

Temp SENDER is at the rear of the head on the driver's side.

Temp SENSOR is down on the side of the block, forward, driver's side.
