Would anyone happen to have an untouched ‘68 4 spd B body that they could take a picture of the firewall bulkhead connector for me?

I put together a ‘68 RR that had been apart for forty years. All new M&H wiring was used front to rear. The car is a late ‘68 with the Hurst shifter with dash mounted reverse light. The ‘68 manual doesn’t have the schematic for wiring the dash light and M&H doesn’t know how to set it up either. As of now, I can get the dash and back up lamps to light up if I put the one “extra” lead coming off the new back up lamp harness to the starter relay battery positive terminal, but they obviously won’t turn off that way.

Any help would be appreciated 👍
