[urq] Coolant Temp Gauge install

[Justin Riley]

This long weekend I had the time to pull the instrument cluster and fix
my broken odometer.  JB Quick solved the split gear slipping problem and
my odometer now registers miles.  While I was in there, I decided to
remove the stock boost gauge, and replace it with the temp gauge from a
4000q.  Cleaned all contacts,  freed up the adjuster for the fuel gauge,
and removed the bulb from the blue (cold engine) light.  All back
together, I drove it to the gas station this morning, filled up ($45
worth of Premium 93).  My fuel gauge now goes all the way to full.  (So
2 problems fixed)

 

My newly installed Coolant Temp Gauge does not register anything at all.

 

So I checked the connections at the back of the head, they look clean.
I tried grounding each connection, but no joy.

 

I cannot find my Bentley at the moment to trace wires.  Any suggestions
(or Copies of the applicable wiring diagram sections) appreciated.
