I present the 400,000 mile PSOM/Odometer

So... everyone said it couldn't be done. But, the van was about to roll over to 400,000 miles and I didn't want to roll back from 399,999 back to 300,000 and be a lame-o. So I figured out a way to get it to show 4xx,***. It's really just a cheat, but took a little doing and looks pretty sweet.

There isn't really a way to make it officially work yet as the LCD doesn't seem have the required bit to make a 4. It is interesting though, the screen may actually have it I discovered, but I couldn't confirm 100%. There are 27 pins that connect to the LCD screen from the PSOM with 27 wires, but there are actually 28 wires, just one of them doesn't go the entire way and ends before it gets to the PSOM connector. That might be the missing bit but I couldn't get it to work. I'm going try some more experimentation soon to see if I can.

Anyway, here it is. Right now it should actually be a 3xx,*** but this is in preparation for the next 1,526 miles and the roll over to 400k.



So if you're asking how I did it. Pretty simply. I printed a 4 on some sticky transparency paper with a laser printer then disabled the 3 on the LCD screen by essentially cutting their wires and put the transparency with the 4 over the screen. Took a bit of touchy work and a couple redos as the sticky clear paper is very easy to mess up and hard to get it to sit just right.

Anyway, I think it's pretty sweet. If I ever make it to 500k I'll print another I suppose and redo it. Or if I figure out how to make it work for real I'll just do that.

I suppose the only way to make it work correctly is take apart a PS dash.

What is a PS dash?

I like the motivation and ingenuity to have the 4 showing

I thought they rolled back to 300k when you hit 400k? I know the super duty trucks do that anyway, not sure on obs or e series.

Rock

I think the 87-91 rolled over at 99,999 miles, the 92-96 roll over at 399,999 miles, and the 97+ I'm not sure where it tops out.

correct before 92 they all rolled over every 100k

That's awesome! You'll be switching that 4 to a 5 before you know it.

I see you put a pickup cluster in your van to get the factory tach. Looks great!!!

I just grabbed one from a ewe-pull-it. Although I think the pickup spent most of its life driving through fields. It’s super dirty and the plastic cover is cracked. Oh well, goes with my beater.

What’s really cool is your family put the entire 400k on that van right? Between you, your dad, and your brother.

They sell new clear lenses for pretty cheap.


and yeah, my dad bought it back in October 1991 or something and we've been driving it ever since. Hope to drive it as long as I can. Drove it to Kennedy Space Center today with the family, she drove like new.

Thanks a bunch for the link.

Yeah my '90 F350 rolls over ever 99,999....becomes a new truck again at zero!
But that explains what was going on with my '92 F250. at about 399.999 it got squirrely & "acted up" I thought. I just figured it was just messed up!!

My '92 got a bit "BENT" in front end when I was letting my 9 yr old GDaughter do the driving & that big, BIG, SUPER BIG boulder jumped out in the road & we/she hit it.
Truck been sitting for last 4 yrs so I don't remember what mileage shows now.

So the 92-96.....when they roll over at 399,999 what they usually roll to?

It just goes to 300,000. Nothing special. There is a video or two floating around somewhere of it.

My 86 goes to 99,999.9 then back to 00,000.0,
Now if i turn back my odometer to sell the truck or any other vehicle, there is a federal law to make it a federal offense.
If Ford does it, then it`s OK.
I actually have 331K.
