I'm sure this is answered somewhere here but I can't find it. On the Grand Prix tach, which side is V6 / V8? I need mine in the V6 location.

🤦‍♂️ How many times I've posted here only to be shown something that's in my service manual. I just didn't know where to look. Yes, exactly what I needed. Thank you!

You can see what I'm doing in the pic - I made a 'jumper' out of a washer, 4-40 screw and nut. It would last, but I really only need it to last until my 350 is in... I bought a new circuit board for that, already set up for V8.
