When I did my SAS I took out the wires that lead to the diff, but now I don't remember where it plugged into. I need to short the wires so my dash light comes on. Can somebody tell me where it is at the firewall?

 

This is from a 95 schematic. I think if you jump A5 you will be able to complete the circuit. Hope this helps out.

Thank you, I'll take a look.

 

Did you figure it out? I need to do the same thing.

 

I need this too - even though I'm still IFS, I'm running a non-ADD diff up front with my ARB.

 

haha.

No, haven't found it yet.

 

Ok heres an Idea since I figures out how the ADD works on my 92 and what I would do if I SAS'd to make the light in the dash work.

There are 2 vacuum relays on the passengerside innerfenderwall, One of them is turned on with the ignition and then when you change the Tcase to 4h/2l it turnes off and the other turns on.
Well with the SAS you dont need ether of these or the little tank under the passenger fender any more so take them out and save them for some later odd mod.

Here we go, Hook a relay to the connecter that went to the second vacuum relay and pull the wires up from the switch that was on the ADD axel and connect it to the N.O. secondaries of you new relay.
Now when you change the Tcase to 4h and 2l it will kick the relay and your Dashlight will come on and the ECM will be happy as well.
Its really easy.

You can also use this relay set up to turn on any airlocker pumps or valves.

To bad they dont make vacuum lockers, Things would be so much easyer, But I think so your not sucking gearoil into your engine by accident.

 

I guess I will need to look for these vacuum relays.

Need pics

 

Great, all that crap is in a pile on the floor of the shop from when I gutted the engine bay...

 

Heres pict, Passenger side inner fenderwall.

I belive the red connector is the one you want, It goes hot when the transfercase is shifted.
No I didnt get a pic of the switch on the ADD axel, It wouldnt help those that SAS. Just pull the wire harness up and do what I mentioned above.
