I've got an innovative lc-1 wideband and my hptuners eio cable will be here within a few days. I had the bung welded into my x pipe which unfortunately is after the cats and before the muffler. Can anyone tell me EXACTLY how they hooked it up? which wired go where etc. Thanks in advance.

 

Can't help on the wiring but I can say that you don't have to worry about the location you have for the bung. It'll read fine.

 

I don't have the Innovative model but most/all the wideband kits are nearly plug and play. The harness from the wideband will come with the proper connections for a "one wire" hookup. Since the Innovative uses a hand held monitor, I would think it only needs batteries, no tapping into a 12V source and ground.
Now if you want to hook the wideband up to your stock computer for narrow band monitoring, that is a little different. The kit should define how to do this tho....
