Intermittent short (blown fuse) of ECM/TCM cable

For 8.1L chassis intermittent shorts (blown fuse) on the ECM/TCM cable running from the under hood (chassis) fuse block up to the ECM/TCM area check the metal harness cable clamp attached to the drivers side on the top of the radiator housing. The clamp has an 1/8th" right angle upright tab on the flat portion bottom of the clamp that slowly cuts into the cable harness.
Anyone with an 8.1L chassis should check and replace the clamp. It will
save you a lot of grief. My symptom was the 10 amp fuse for the START circuit would blow and the starter and solenoid would not operate.
