There goes my
reading comprehension fault again, you Clearly said 6-speed didn't you?
And frankly, I'm not sure how that circuit (you don't
have an OverDrive sw) is associated with the TPS & Cluster, but it might be somewhere else...
You're really better off checking fuses with a meter, "visually" can be unreliable and sometimes fuses that Look Good can actually be either Open, not connected to the fusebox solidly, or passing too little power to keep downside stuff running right.
As for your code (P1290) makes me suspect that you're not using the right equipment for our trucks. There is no 1290 because there is no cly head temp sensor. The right scanner might find a more relevant code but, more importantly, would allow you to read the TPS values to confirm it's communicating with the PCM.
My Usual Scanner Advice;
If you're gonna keep & maintain the truck yourself I strongly suggest you get access to the special scanner software you need to do it.
To retrieve most of the codes you'll need to help and even do
some testing look at the FORscan Lite or TorqueApp (you add an Android device and Blue Tooth Adapter for @ $30) OR the Windoze version with a USB adapter. I like this one for BT Android ->

Just a few years ago you needed to buy a professional scan tool because our trucks need to have a scanner with a Library containing both the Ford Proprietary AND the Diesel Specific codes in it. Add to that, our trucks are Not, specifically, OBD-II so the Generic scanners the Auto Parts Stores have are of little use to us. But today there are some very good App based tools, that are close to what the pro tools do, for fraction of the cost.
