I replaced a faulty pre-glow wiring relay with a manual system which solved electrical charging issues I had.

Now, however I have a non-functioning temperature unit in the instrument cluster. That makes sense because the wiring for the cluster goes through the glow plug relay.

My question is: Does anyone know how the reattach the wiring from the temp sending unit on the side of the block to the instrument cluster so the temp guage will work?

There are actually two temp sending units on the side of the block. I believe the one toward the rear of the car is the one controlling the temp guage.

The small plug originally attached to the relay is available to attach the temp sending unit but the relay muts have changed the signal to the unit or something.

Anyone know?

Thanks.
