Hello everyone. I have a few questions about removing the engine harness on a 1995 K1500. I know you have to disconnect part of the harness at the bulkhead on the driver's side and that the other side of the harness passes through the firewall on the passenger side which goes to the ECM, but is there a connector in the dash for the CEL and ALDL port or would I have to pull the dash to get that wiring? Any help would be appreciated. Thanks!
