Rated 4.5 out of 5 stars.
Got a 7.3L IDI diesel in your old Ford truck, whether it's turbo or not?
If you're having cold start issues, the glow plug system is usually the culprit.
This is a brand new controller and relay combo from AutoExpert, designed to replace that finicky factory unit on 1987 to 1994 models.
It's a direct replacement, and we've cross-referenced a ton of part numbers for you: it fits OE numbers like DRX01001 and E7TZ-12B533-A, plus interchange numbers like ZD-8 and ZD-9.
Just get this bolted in, and you should be back to firing up reliably on those chilly mornings.
It's made for diesel engines, so it's built to handle the job.
