Hello, I need a bit of help. I do not know how to connect the wires to my meter board. Any pictures?

Hello, yes, I can see this, but what I mean is the meter board I have is a very early one, and it's not the one in the service manual. That one shows 2 IC control chips, and mine is not like this. I was hoping had a photo, but thanks, Duke, for the response.

Hi Robbie,
Narrow it down. You'll find a common (ground) and a supply. Probably positive. You may have a negative supply, but for sure a signal from each output section. Look at the board, you'll clearly see where common and supplies go.
