6.9L Ford / IDI Glow Plug Controller

Made in the USA

Fits 1983 -1987

This 6.9 glow plug controller is an updated solid state design. The original sensors were electro-mechanical and had an extremely high failure rate. Our replacements have been re-engineered using modern electronics technology for much improved reliability. Externally the sensor will appear unchanged and will plug in perfectly with no modifications. Operating characteristics have not changed. If you need to diagnose the system after installing our IDI glow plug controller, please keep in mind that continuity tests published for original electro-mechanical style sensors are no longer valid.

Note to 1987 owners: Some 1987 trucks will have the later 7.3L style glow plug system with a rectangular style glow plug controller and bullet terminal glow plugs. 1987 owners need to check which glow plug system their vehicle is equipped with prior to ordering.

We also carry glow plugs, glow plug relays, and glow plug kits for your 6.9L engine.

NOTE: Please be cautious when replacing one of these 6.9 glow plug controllers - they are hollow aluminum and will easily break if overtightened.
