I tried to remove the varible resistor from the board and extend it with wires.
I screwed it up. At my age, it is very seldom I can use my hands as well as I did only 5 years ago.
So I attached the entire board to the dash and used wires to the gauges.
I took a bunch of photos to post. I will wait until it works perfectly before I post them. Now I am taking a break before I put it back in the dash. More later
FYI, I ordered 5 more regulator boards at $1.15 each
