I need an 85 Cali 300D wiring diagram

I shorted out something around the fuel gauge area while trying to install my new led lights for the cluster. I found one spot that was fried and jumpered it (see pic), but it didn't fix the problem. The issues are; no power to the left cluster light, fuel gauge erratic (rises and falls with the hazard flash!), and when I try to install a light in the right cluster socket, everything lights up (blinkers, hibeam indicator, other indicators)... Can't seem to find any other visible issues.

I want to take a look at the wiring diagram to help he determine if I've created any other more serious issues back up the wiring harness somewhere. I REALLY hope not!!!

I'd start by running a new ground from the cluster to the chassis. I attached mine from one of the bolts holding the speedo in place.

here's a wiring diagram
