Where did you guys run your wires from the wideband module to the acutal O2 sensor in the down pipe? Is there a hole like the one going through the firewall in the floor I can use or do I need to use the firewall hole?

 

There is a oem hole above the clutch pedal to the left, it has a black rubber plug it in.

I used that for several things actually.

 

Over the transmission and into the driver side of the engine bay. (lots of zip ties to keep the wires out of harms way) I punched a small hole in the very elastic rubber boot for all the ECU wiring I think and fed it though that.

I pulled all the pins from the plastic harness clip and put them into the butt end of a bic pen that had the ink tube removed. The wires were taped at the butt end of the pen so they would not fall out and the pen was then forced through the rubber boot into the driver side footwell. I then pulled the wires out of the pen and put them back into the plastic harness clip. Then the went behind my seat for the EMU but you may be running them to a different location.

 

Yeah, this is the one I've used for absolutey EVERYTHING going into the engine bay, but I'm wondering if there is another one that I can use so I can run my wiring to the oxygen sensor directly that is closer to the passenger side. I'll most likely have the module under the dash on the driver's side.
