Car is back together, now WB doesn't work?
 

So I finally got the car back together, it started up like a champ, but now it seems like my WB isn't getting any power. I have it wired up in the same way as this. I checked the ENG SENS fuse and it looks fine. I tried hooking it up to all 4 stock NB connectors all with the same result. I don't have access to a multimeter right now so I can't test the 12V from the NB connector. Does anyone have any idea what it could be?

Thanks in advance,
Kevin

Update: There seems to be a short or something in the O2 connection somewhere. I hooked the WB up to a new 12v source and ground and it works fine. So now I need to figure out where the problem is in the O2 wires. I just completed a H/C swap, could it be one of the grounds on the back of the head?
