Today I went out to my truck to get it warm before heading to work and I happened to look down at the odometer and it was blank,and as I took off for work I noticed my speedo is no longer working.Everything worked the last time I drove my truck,i'm thinking maybe a bad ground,and I did replace the fuses,and everything else works,but occasionally my tach will bounce for a second.Any idea's?

Lucky you have a ZF in there, or your transmission would be giving you hell the whole ride home too.

Yes, there's about three open topics about the PSOM right now.

If it has a manual, and it was stock to that truck, it's an M5OD.

You would have had to swap a ZF5 in there, as they were only offered behind the 4.9l in one year, and in the F250/350's.
