Multimode transfer case to standard J-shift

[MandAtaco]

Pin 13 is a Yellow/Red going to the "A/T INDICATOR LIGHT SWITCH (PARK/NEUTRAL POSITION SWITCH)"

On a 5-Speed this goes to the CC switch on the dash, which I guess the A/Ts don't have? Maybe THIS is your issue.

The green/orange wire leaves the Comb. SW on Pin 3 and goes to Plug 3E Pin 8. Then it splits into FIVE more green/orange wires that leave on the same Plug 3E as follows:

Pin 7: Diff Lock ECU
Pin 5: 4wd ECU
Pin 6: AC Amplifier
Pin 4 : CC ECU
Pin 10: ECM

So I don't see how the 4wd ECU disappearing would have any effect.

Thanks for some more clarification on the where the wiring goes. If the cc module is in fact getting its own speed reference, then I'm sure I didn't lose it through the 4wd computer then.

Ok, what you said about pin 13 yellow/red going to the a/t indicator light switch got me thinking. This switch on a multi mode case truck goes into the 4wd computer, not directly to the CC module as it does on a j-shift truck. I think this maybe what I'm missing.

I should be able to tie pin 17 of the 4wd computer to pin 16 of the 4wd computer and basically wire it the way a normal J shift truck is wired. See highlighted pink in pic.

I would think so. You then don't have a master switch like you do on mine, but then, why do you need one? There are lot's of ways to disengage the CC, so I really never understood what that dash switch does. I guess it's a safety if the thing goes into poltergeist mode and refuses to disengage. On an A/T you then switch into Neutral, and I guess that kills it? (I don't know how that switch works, I don't do slushbox.)

Gonna hook it up tomorrow and see what happens, comparing j-shift schematics, multi-mode schematics, and CC schematics, that seems to be the disconnect.

Yea I don't even know what master switch you keep talking about. LOL Must be a manual thing. Mine is all controled on the steering wheel stick.

Thanks for the help, I'll let you know what happens. Thanks Durk!

Yeah, the EWD says that switch is M/T only.

Yup, that was the trick. Had to tie pin 16 and 17 of the 4wd computer together to complete the circuit to the CC module. Everything in the truck officially works as it should! :whoo:

Thanks all! Especially [MENTION=10169]TheDurk[/MENTION] for help with the schematics.

I'm in the middle of a j-shift swap as well and I had a few questions about it
did you leave the 4wd computer plugged in or just junk it

from what I understand
5-way relay to run the vsv's / on or off for front diff
you can tie the dash light to the 4wd vsv circuit

cruise control jump pin 16+17 to gain cruise back
is there anything else?

My multimode has had a drive identity issue for a long time
thanks guys

The Green orange line is cutoff wire. It's meant to cut off ground to certain systems depending on the position switch on the trans or transfer case...

For the locker, stop engagement
For the CC, disengage/stop engagement

Bottom line is, by tying the wires together, you've effectively cut out the safety feature for the transfer case 4lo cc cutout... If you go into 4lo now, the cruise control can inadvertently be engaged, the cc won't cut out like it should.... I think you can see how this can be bad to rev up and get stuck there or increasing speed when crawling in 4lo...

Not sure I follow... This is exactly how a regular J-shift truck is wired, so why would it work there, but not in a converted truck?

Relay

Just to update this thread, I successfully swapped from the multi mode to the J-shift and got the front diff and dash lights to work, simple relay did the trick.

I noticed this morning though, that my cruise control doesn’t work. The light comes on the dash, but I can’t set the hold speed. Thinking maybe it looks for some signal from the 4wd computer that I took out. Does anyone have a schematic for the cruise control circuit for a 2000 4Runner with the multi-mode case?

Thank you!

Question I’m completing this myself what really did you have to put in and where did you have to put it in. I cannot get the front diff to lock in 4x4
