Multi-Mode Operation Question (99-00)

dhmenheere said:
I am guessing that Pin 6,7,9 & 18 require wires to the transfer case motor and detection switches. Does anybody have a picture of the switch locations on the multi-mode transfer case? I can take a picture and post it up tonight but at "work" now.

Also Pin 1 has no connection but Garagebuilt routed these to the ADD on the front axle?? Looking at the wiring diagram I get the ADD(99) = 4WD(96) which is Pin 19(99) to Pin 6(96)?

help

I wish I would have kept my wiring diagrams around but unfortunately I threw them out hoping to never do another swap like this again. When I am at work let me see if I can get you a better wiring diagram to work from.

Although I never used Singtoe's chart he had posted in one of his previous posts about the swap, I think that if you followed his wiring method everything would work. I went a little over and above by splicing into more of the factory harness getting signals from the ECU, ABS ECU, Cruise etc. Like he said the transfer case can work independently.

Thanks Garagebuilt, Singtoe for the reply, I will probably just go the simple route in my swap and connect the minimum. Did the old transfer case electrical plugs match the new transfer case?

See attached picture if anybody can tell me what each plug does.

thanks!

I hope this works!

Number 5 is the center diff look switch (when the lever is thrown back)
Number 1 and 2 are the neutral and low indicator switch. I think 1 is neutral and 2 is low indicator.

Number 4 is the Actuator hook up.

Number 3 and 6 are the indicator whether the center diff is locked or unlocked. Lets the ECU know that it is engaged or not. I don't rember which is which.

The actuator has a big spring in it. When it engages the front drive shaft (AWD) or the center diff lock (4x4) (shaft does both), if the cogs aren't in line the spring keeps tension until the do align and then slides in.

This is why it seams as there is a delay from the time you engage the 4x4 till the light shows up on the dash.
 
Thanks Singtoe!

If I've read right I could replace Number 5 with the dash switch from a 2001-02 4Runner and if need be put a light on it to indicate center diff locked.

I will clean up the wires and see if I can make out the colors. Does anybody know if the connectors are the same?

I had an entire body harness from a 99 which was included with my transfer case so that is what I had used. From your picture I can verify that plug #4 can be reused, there is one ground wire that you have to switch pins. I believe you will also run out of connectors but from what I remember they will work but the wiring needs to be extended due to the difference in length of the case.

ok, thanks for everything, I'll crawl under and take a look when I get a chance. I'm hoping the extra plug is for the center diff lock but we'll see.

Are you saying to use a transfer case out of a 01-02 4runner or use just the switch?

If you are using the 99-00 transfer case, go ahead and use the Switch on the transfer case.

The 01-02 center diff lock is a momentary switch and will need a latching relay to work. It took me 5 relays to make mine.


The center diff lock indicator is the rear housing of the actuator. Use this or the output from the 4x4 ECU for your dash light signaling a locked center diff.

If you use Number 5, as your indicator source, it will give you a false interpertation as the center diff might not be fully engaged.

Thanks Singtoe, that explains alot. I took a look at my old transfer case and it does not have the connector at location 6. There is a boss but it is not machined for the sensor. I'll try and find a harness or extra plug at a junk yard.

Anybody have a harness in the Toronto area?

thanks again Singtoe and Garagebuilt!

I just purchased a 2000 limited and there's a hose from the actuator on the transfer case just hanging. My 4x4 does not work. Where does this hose go and would it affect the 4x4?

Banjo,

I went to look at a used 4Runner the other day, it was a 2000 SR5, and was stuck in 4WD after the ABS controller had been replaced. I crawled underneath and found the hose I believe you mentioned hanging loose and an empty port on the bottom of the actuator. I plugged the hose onto the port on the actuator, and it had absolutely no effect on the stuck in 4WD issue.
The center diff lock indicator on the dash was flashing amber and the 4 wheels were illuminated green no matter what I did with the 4WD button on the shifter, the position of the shifter itself, or the center diff lock button on the dash...
 
My hose was attached to the actuator but couldn't find where it went to. Finally found it after taking shifters out from the inside of the truck and there's a port on top of the transfer case. I plugged it up and still no 4x4. I read a thread recently about swapping a multi- mode with a j-shift from and older 3rd gen but can't seem to find the thread now. I had an older parts 4runner so I swapped transfer cases. Everything plugged up as it should except for the actuator since the older ones don't have it. Still no 4x4....
