So after I fussed with the 2-4wd vacuum control and hoses, now my temp guage indicates nothing. I assume I knocked off a connector or broke a wire.

Where is the sending unit and what did I most likely do.

I was under the battery support shelf, I was tugging the vacuum hose that runs from that actuator under the shelf and following it up across the engine to behind the distributor on the firewall.

Suggest a place to look for a loose wire I bumped in those areas.

Thanks.

 

So I fussed with a couple connectors on some type of sensors in the area of where I was messing with the vacuum line and the gauge worked again for just a bit. So I know where I have to look more closely.
