How hard was it? I have a 4.7 dodge Dakota four-wheel-drive quad cab and the electronics for the four-wheel-drive is always going out so I’m trying to bypass it. I have a transfer case for my 5.2 Durango and the shifter for the floor four-wheel-drive.
4WD bypass surgery. No more electronic junk
2001 Dodge Dakota 4.7 Automatic with Electronic 4WD shift.
So I finally got tired of fooling around with the TCCM and all of the electronics on the Electronics Transfer case junk and bypassed all that junk and now have an easily shifted transfer case. No codes, no electronic modules, no dealer flashes and charges $$$.
So simple even a cave man could do it!
More on this if anyone is interested.

It was not hard at all.
I cut the wire leading to the transfer case 2wd/4wd actuator motor.
I then stripped the wires on the motor side and connected two wires long enough to be routed along the frame, into the engine bay, thru the firewall and under the dash.
I then located the Fuse that provided power to the electronic 4WD. I then ran a red wire from that fuse under the dash near my 4wd switch leaving a little extra length.
Also: find a good ground and run a black wire from that ground area under the dash along side the positive wire.
This is important: Buy a momentary reverse polarity switch. The switch needs to be momentary/center stop/momentary reverse.
As for your wiring you will need a positive lead which you have that wire ran already from the 4wd fuse, a ground, the two wires that you have spliced into your transfer case actuator motor.
Remove the stock 4 WD switch from the dash and disconnect it from the connector.
Fish all of the loose wires up under the dash and out of the area where you removed the switch. Connect the red and black wires to the center lugs and the wires coming from the transfer case one to the left side of the switch and the other wire to the right side of the switch.
Before re-assembling the dash test the switch.
Start the engine, shift into neutral.
Move the switch to the left and you should hear the click shift at the transfer case.
Put the truck in drive and test the 4wd.
Switching back to the right should put you in 2WD.
Things to remember.
Shifting in this manner will be rather trial and error until you get used to the shifting sequence.
Also: Make sure your always stopped and in neutral before shifting. No more shift on the fly.
I took the extra precautions and ran my wires in wire loom.
Your 4WD light will remain on since you no longer are using the TCCM etc. ignore it!
I also placed a racing type flip up cover over the switch. This protected the switch and eliminated accidental shifting.
If you are mechanically inclined and under how the shift actuator works you should be able to do this.
I live in NC and I’m a retired mechanic. If your near and need help let me know.
If not message me and I’ll get you on track.
Good luck.
