Help with ADD 4x4

So I’m looking to find out which vacuum line engages and which disengages the fork on the axle for the ADD system. I have a basket case 95 4Runner with a 3.4 and 5 speed from a 99 4 runner and a 95 T100 ecu. I get no 4x4 light but that could just be from the swap. I just really need to know which side I need to apply vacuum to get 4x4 working until my manual locking hubs show up and I lock the ADD fork into 4x4. I have vacuum on the green solenoid for add but not the brown when I switch to 4x4 but I’ll just switch hoses around once I know which way is which. Thanks

 

It’s the passenger side hard line directly off the ADD that engages the fork in case anyone else ends up needing this info. My manual locking hubs came a day early so I installed and permanently locked fork in.
