Our tuning backlog is longer than normal going into October and additional delays should be expected. Please email with any questions.
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.
