*fwd fuse.

Do 99 have the fed fuse? If so pop a fuse in and see if it goes away, if so it's the center diff for sure.

Original sensor has 4 wires, most aftermarket are 3 , missing that grey ground. Cel is off, grey wire not connected.

I figured it out.Bosch 3 wire is signal(black), heater+(white)and heater-(white) . 4 wire is all those plus sensor ground(grey). Anyone have any experience with switching the 4 wire for a 3 on the downstream?

I'm trying to install a bosch universal 3 wire 15726 downstream o2 on my gf's 97 legacy 2.5 but the org. Was a 4 wire? Anyone else run into this? It's a bosh 15726. Thanks!
