Hello,

I tried to figure out why my temp gauge does not move at all (I even grounded the wire) and I've got two questions.

Question 1
On the electrical diagram, looks like there is a light and dark green wires going to the sender. On my truck, it seems the light green was cut at firewall and I've got only the dark green going to the sender.

For what the ligh green is usder for?


Question 2
At the back of the cluster, I've got the feeling the board as a damaged on the second picture, please see below. Is there a way to wire directly the gauge without going thru this motherboard?
