What if you have the R180 on your wrx and want to wire it up to the sti cluster as well to make it work?
If the diff already has a temp switch in it, then it should have a connector with two wires on it. Since it is basically a switch, it shouldn't matter which wire you use so pick one and send it to ground, and then send the other to the B4 terminal in the cluster. If the temp switch only has one wire then send that to the B4 terminal in the cluster. From what I have studied in the manual, the switch should have 2 wires, one green and one brown. In the wiring diagrams the brown wire goes to ground and the green to the B4 terminal.

UPDATE I drove the car today on two 20 minute trips and the fix is working perfectly. No smoke, sparks, fire, explosions etc. coming from the cluster during sustained operation, which is always a good sign
