[urq] minor electrical gremlins

[Gary Brown]

Guy..
I'm still kind of chasing my warning lights issue. I can't seem to get the coolant and oil lights to come on, even if I ground the sensor ends of the wires. Nor if I jump the plug on the coolant tank switch. All of the other lights work as designed. 

Also, my rad fan stopped working, but if I jumper the plug on the lower rad switch, it comes on, both speeds. Are these lights and fan issues related? 

 I have a switched power BK/BL wire behind the cluster that I have no clue where it goes. Bentley says T10/8. I tried it, but the working lights stayed on. 
 I have a temp gauge in place of the boost gauge. I think I used the blue light wire to operate the temp gauge. Don't think thats the problem, but I don't know.
TIA
