YJ91´instrument cluster wiring HELP - Pirate4x4.Com : 4x4 and Off-Road Forum

Hi there pirates
I need some help with the instrument cluster wiring of my YJ 91´2.5L, with the five instrument cluster (LtoR : water temp, gas, clock, oil press and volts).
After an engine rebuild, My water temp gauge has gone dead and I don´t know which is the wire that goes to it of the big connector on the back of the cluster.
It does not seem to be the sender that have gone bad as the ECU detects the sender and corrects the idle when I connect and disconnect it, aslo I have tried with the two senders I had at hand.
Therefore it seems to be or the wiring from the sender to the instrument cluster or the cluster itself. the rest of the instruments work OK.
Thanks

Eduardo

there are 2 water temp sending units, one is for the computer, the other for the gauge, look for the one that is just a post, not a plug.

The only one I was tinkering with is on the head on the front left side and has a waterproof connector in it. Where is the other one ?????

I hate to admit I forgot about that thing that looks like a screw. Humans tend to ASSUME things... I assumed that the one in the front was the ONLY
sender.
I have gone to my place´s shop and checked the old engine and IT HAS THE sender in the back of the heads NOT the front like the computer one.
Tomorrow i will go to the garage and check the "new" engine in the car...but I am sure that I forgot to connect it, there must be a connector hanging around there.
Thanks

for the two sender comment
