Has anyone made this swap? I took a wrecked 96 302, auto 4x4 and I am replacing my 300 ci 5speed 4x4 drivetrain. I know that the harness to the engine and to the transmission are different. I have also chaged the ECU. The truck runs but has a rough idle. I changed plugs, wires, etc. before the swap on the 302. Does the master fuse harness also need to be changed? Does the column harness need to be changed due to the neutral safety switch? Please, any imput would be greatly appreciated.
