The stock 6.5 glow plug harness is pitiful at best, after 200k miles they are basicaly used up so when I did my Dually engine swap I made a complete new Harness I used Mil spec High Temp 12 ga wire new Packard ends and used heat shield wherever it got close to the manifolds, I did not put the fused links But I used Bosch glow plugs so they are proteced there
