any idea where to put the controller for the LC-1? That cable from the WB sensor to the plug is extremely short.... Is it water proof and can be outside somewhere under the car??

At the moment, mine is all loose since I'm waiting for some connectors that I ordered.
Yes, it's a weatherproof connector.
Some places:
If you got a 3 pt SFC, then ziptie it there.
If you got headers (so WBO2 cable reaches), then on upper side of trans. cross member.
Ziptie to fuel/brake line bracket/clamp.
Ziptie to A4 shift cable.
Up in trans. tunnel.
Make a bracket from a strip of sheet metal, fasten to A4 pan bolt (similar to A4 shift cable bracket), and ziptie to this bracket.

Thanks.
Thanks.
LC-1 analog ground (green) goes to 2 places:
a. analog ground of logging device (EIO, FlashScan, ...).
b. HO2S Low Signal (pin A) on NBO2 connector on vehicle harness.
NOTE: HO2S Low Signal is different than PCM ground.

Joe
Edit: LOL, I fixed my really dumb typos...

What do you guys mean by pigtail on hptuners. My tuners cable all the wires go into the connector, there is no "pigtail" hanging out to hook my wideband up too? If so where would I hook into it, I don't think I can.

Awesome info, thanks !!! 
Glad I kept those old dead O2 sensors - I will grab the wiring connectors off a couple of of them to use for this.

OK, I figured out the problem I was having yesterday when talking to a bud of mine. The NB wire on the NB is actually connected to the body of the NB. I checked it with my DVM. Therefore, when you install the NB, it in effect grounds itself to the engine via the exhaust pipes.
So, when installing an LM1 or LC1 and using the NB sim output, connect the output to the purple NB high wire that goes to the PCM, and connect the NB low wire that goes to the PCM to the WB ground wire and a chassis ground point. That will allow the PCM to read the correct sim NB output.
