I tried it on my 02 250.. works great...

 

Good!

Lots of possibilities here!

 

I just did this to mine and it worked fine. Other than the jumper wire I accidentally from from the check gauge light to the glow plug light. I wanted to get the glow plug light to light up on a gas truck, which it does, except it never goes off until after it starts. It also stayed on in with "Check Gauge" in the test mode.

Question though: Does anyone know what the number means in the first video at about 1:25? 3023743 showed in the video. Mine showed 7796351. I didn't see anything about just numbers.

For kicks & giggles, I ran the same type of test on my dad's '04 T-bird. It had the same number, and his is 560018. Mine has 128,603.4 miles on it and his has 126,011 on it, so the mileage is very similar between the two.
