I have the NP 203 transfer case with a part time conversion. I don't know what the shift pattern is to begin with, but I heard it's different with the conversion? What would be the normal driving position? 2 Hi?? What is 2 low used for? I haven't been able to take the truck for a spin yet to test it out, due to an electrical problem I'm battling. As dumb as this question seems, keep in mind this is my first experience with a 4x4.

 

The 1st pic is your NP 203 pattern (full time 4 wheel drive no lock in lock outs) but since you now have the conversation kit on the axle (lock in/out hubs?) and in your xfer case.

You should be able to run in 2H until you need 4wd, lock in hubs, put in 4H for driving on gravel/snow loose stuff at faster speeds NEVER ON PAVEMENT !!!!!

And 4L for real slow driving and getting the power to the ground, stump pulling, heavy load trailer stuff, pulling out chebby's off wet grass lol.

The 2nd pic is NP 205 part time 4 wheel drive, which you should have now, I would swap the ****.

Also remember to always back up a bit 2 or 3 ' when you unlock your hubs to ensure they are unlocked.

Fords can be a little tricky when going from 4wd(4H) to 2wd(2H), if you miss 2wd and go into neutral and if it grinds when you try to put it back in 2wd. Just shut off truck and then pop it in 2wd.

2H for normal driving in rear 2 wheel drive
4H for gravel mud snow loose conditions at faster speeds
N neutral for wrecker towing with front wheels up, rear on the ground.
4L for lower speed more power

You can drive around with the hubs locked in and the xfer case in 2H like when its off and on snow and off and on muddy.

But not all the time IMO, remember you 203 is splash oil lubed chain drive

 

9d4 what year is your truck. The above 203 **** is from a highboy. The 77.5 to 79 shift patter is totally different.

 

my '79 bronco had an NP203 in it when I bought it. I junked it in liu of an NP205. but the shifter went all the way forward was 4L then just below that was 2L, then N, then 2H and all the way back was 4H. There was no dog leg kick out or anything like that. I believe the dog leg shift patterns were in the 80's. the shift patterns shouldn't have changed, althought I would say, a ford NP205 is actually rather cheap to find in salvage yards because unlike chevy, you could get this in half ton Pick-ups. with a chevy you'd have to get a 1-ton truck. so just look for a good NP205 (they are bomb-proof, if you can tear this transfer case up you could ruin a Sherman Tank) then you'll need to cut 4 -6"s off your front drive line, and get the rear one lengthened by 8-12"s. Or if you can find the drivelines off the parts vehicle, steal them too.
