Due to high demand, current lead time on tunes is minimium of 2 weeks. Current lead times on custom built turbos is ~1 month. Please plan accordingly. We thank you for your support of the finest parts available for the 6.5L Turbo diesel platform!
Glow Plug Harness
Genuine, upgraded, replacement glow plug wiring harness for all 6.5L diesels.
- NEW for 2018 - Exclusive ceramic connections to protect the harness near the exhaust manifolds.
- 12ga high temp wire, all protected by fusible links and heat shield
- 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
Two styles are available for different trucks. For 1997-1998 models, we recommend taking a few minutes to peek at which style harness connection you have since there was some mixing/matching at the factory depending on build month.
- 1993-1996 With one wire that needs spliced to trigger the glow plug light. It is on the drivers side bank of wires.
- 1997+ With a plug-in trigger wire at the engine harness bulkhead, under the fuel filter manager.
