Heavy Duty Glow Plug Harness

Genuine, upgraded, replacement glow plug wiring harness for 6.2 and 6.5L diesel engines

• 12ga high temp wire, all protected by fusible links and heat shield
• All connections are crimped AND soldered
• Longer length to allow better routing like GM did on late models
• The passenger side wires route across or under the intake, in front of the cylinder head, then back to the glow plugs
• Eliminates the small extensions the factory used on passenger side wires
• Cross compatible with the older pre 1997 and later 1997.5+ configuration since we include the option to splice or plug in the indicator light wire depending on the model year (Both configurations shown in the photos)
• Black high heat insulation on all wires

Fits : 6.2 and 6.5L diesel (side mount turbo) engines regardless of model year. This is a universal fit that may route differently than your stock harness did.
