OK... BUT HOW TO 'SIMULATE' THE SENDER ON THE GAUGE AND TURN ON THE LED'S 
WITHOUT CONNECTING THE ACTUAL SENDER?

BEFORE IT GOT STUCK ON 60 DEGREES, IT WAS READING WAY TO HIGH TEMPS AND 
EVENTUALLY SHOWED THE SINGLE RED MAX OIL TEMP LED AFTER 20 MINUTES. I'VE RED 
IN THE ARCHIVES THE OIL TEMP LED-CIRCUIT NEEDS 10.5V - NOT 12V - SUPPLIED BY 
A REGULATOR ON THE PCB. IS THIS TRUE?

YES, IT DEFINATELY HAD.
