Haha I did the exact same thing, I appreciate the pics 92! I figured mine out over the weekend. It's pretty much done except for wiring. Most dreaded to me, I hate it.

[QUOTE=92_cummins_f250;606555]So does it draw from both tanks at the same time all the time then? Must work good but I would still be nervous about not having hard lines .

the dot brake line is petrolium rated so it wont eat away and with it supported to that stiff plate in the tank its vertually a cheap version of a draw straw, no it pulles out of 1 tank at a time its on a deverter valve from the factory in cab switch

Ah ok. I wasn't sure how and what all separated the tanks from one another since I left all that part alone on mine. Good to know though in case I ever wanted to do away with the electric pumps.

Well, my truck is a '79 but should be the same. Locate the plug/wires that went to the ignition box. Find the wire in that group that is hot when the key is "on" and "start" positions, splice it to your solenoid and voila!
Enjoy, Carl

So you splice in the wires that stay hot when ignition is on and the start wire into the solenoid? Did you reuse ford starter solenoid? Thanks!

I reused the Ford solenoid, just moved it to the drivers side of the engine bay. The Mitchell wiring diagram shows two "run" wires, one being gry-yel and the other being red-lt grn. The "start" wire is red-lt blu. The red-lt grn wire goes to the distributor, ign coil, EEC power relay and a couple other major running functions of the truck, the gry-yel only goes to the fuse panel and then to the heater function selector and OD switch. Can't remember now where I spliced into the red-lt grn wire though, cause I'm pretty sure that it goes through the power dist box too. Hope this helps, been quite a while since we wired mine and we didn't really document what we did. Let me know if I can try to help with anything else.

Preciate that 92! How did you wire the od on the dodge trans? Which wire I guess?

Um, that will take some memory and looking at the Mitchell book to see if I can remember. I do remember you need a different switch than the factory Ford OD switch in the column.

This shows the wiring for the factory A518 OD lockout
Den - Dodge CTD 1st Gen Website

And this is how I wired the OD control

The OD control works good, but with 3.55s and 37" tires it shifts into OD a little sooner than I would like. I leave it out of OD in town anyways and then just throw the switch manually if I want it to hold out a little. This wiring is fairly straight forward if you can get the Ford side diagram too.

You should upload some pics of your conversion when you get a chance too!!

So for the od to shift you need the switch or does it stay In od and you use it to disengage it?

I will post em up hopefully this weekend finally got Internet at my new house instead of this damn iPhone.
