Help with Code 0357 on a 1998

I have a 1998 Vette with 80000 miles and the code P0357(ignition control #7 circuit) comes up now and then and I reset and it is good for a time. I decided to change the plugs and wires and still have the same problem. I changed the coil for cylinder 7 with cylinder 5 and the same code came up P0357. Please help, thanks.

Inspect the wiring, especially where the harness goes around the bracket for the knock sensor plug. If nothing is obvious, you will have to remove the connector from the PCM, and check the resistance to ground on ignition #7 circuit.

Behind the left fuel rail (see below). Since this is a common chaff area, I have protect the wire bundle.
