Re: 67-68 Wiring difference
Replacement wire end connectors for the firewall bulkhead connectors can be found at a variety of suppliers. Del City has a good selection.
I integrated an LS1 engine harness into a stock '68 harness. It uses the stock firewall bulkhead connectors to send the OBDII, speed, tach, fuel relay, etc. to the cabin and to the trunk. It's a lot of work, but the finished product is easily removeable for servicing. It is also helpful to make new wiring diagrams of the bulkhead connectors to make future servicing easier.
