I've got a 75 Century GS I just picked up. The speedo lights weren't working so I tore it apart and can only get two working. For some reason it looks like the 5 pin connector only has 1 power and 4 grounds. Looking over the circuit board it looks like it should probably be 3 powers and two grounds. I didn't have any luck finding a wiring diagram online and really hoping to get this thing together today or tomorrow.
I was hoping not to wait on something to ship and get it working sooner. But looks like being an unpopular year online resource are scarce.
There is an online 1975 manual over at https://www.teambuick.com/reference/index.php You have to join. You really should have a copy for yourself, and that Ebay item is a screaming deal. You bought it already, right?
Thanks that was perfect. Soon as I seen the diagram I knew where to look. All lights are working as they should now.
