Just swapped out a 305 TPI to a 383 Stroker carbureted.The digital gauge cluster will light up but wont display. No fuel, volts, temp, oil pressure and no odometer .I'm thinking a common ground but not sure. Any ideas? I'm not an electronics guy.

 

I believe there is a ground that needs to be hooked up in the c207 connector that was probably removed when the tpi wiring was removed. I can look more into this after work.
