Are the glow plug modules on the excursion interchangeable with the 6.0 modules? or are they different? Thanks

 

They look the same,but I think different part numbers. I can get a 6.0 one for 50$ or less. Clay has the 7.3 ones for 120$

 

They use the same pigtails if that means anything. I used the Int'l 'repair harness' (for 6.0) to fix my dually. Make sure ya don't have this problem:

The blue pigtail is the old one - see the melted plastic around the pins?
