I have a 1999 1UZ-FE with VVTi. Im trying to make sense of the camshaft configuration. There are 4 VR sensors , Crankshaft NE, a 36-2 wheel, Camshaft G2, with a single tooth, and two intake camshaft sensors VVL and VVR with 3 lobes at a 135/90 degree separation. Keeping the NE and G2 on the built in TRIGG1 and TRIGG2, I would like to use the SCL, SDA pins as inputs for the VVL and VVR like the picture from the SubaruEj. How would this be configured?

honestly would do ecu upgrade, but it's still possible to do it on that one, anyway fw upgrade to latest is a must :)
3 aditional hall to vr converters + some zeners and resistors
