those look like o2 sensor connectors; if they are the front sensors, you'll need all the wiring; if they are the rear o2 connectors then remove the wiring and connectors completely.

You are absolutely right. They must be the rear one because the front ones are still on my engine unplugged, not cut like these.





Thanks for the quick information on this. One more question on this. Since these are the rear, as you stated, I will not need these at all and you suggest to remove them completely and does this need to be programmed into the PCM when I have that done? I have not taped the harness back up yet for reasons like this so I can alter it in case of need to remove/add something else.

Yes they will be removed in the PCM by the tuner.

Thanks guys. Here are some more updates that I got accomplished today. The DBW pedal and TAC module are in place. To start, the new DBW pedal is larger and longer than the previous TBI pedal. When I first bolted it down using only the factory bottom bolt for the old pedal the new DBW pedal was touching the transmission tunnel. I cut the pedal in half between the "S" bend or dog leg and then slid one over the other and held it together with a visegrip to check how it fit. Now the 2 will be TIG welded back together tomorrow.





Looks pretty natural when looking down from the drivers seat.



I then sized up the firewall plug and matched it to the correct hole saw size. After making the hole and a extensive de-burring, I fed the wire and and plug through. Its a tight fit like the factory would have intended. I then select the place on the firewall to mount the TAC module. Here are some pics of completion.

I noticed you still have the cruise control unit mounted to the firewall. The TAC module handles the cruise function of the DBW setup and mounts directly into the same location as the cruise unit.

Thanks, wish I would have known that earlier. I am glad that I don't need that thing and it will get removed immediately when I get off work tomorrow. Any advice on how to incorporate the factory cruise control functions in the cab to make this work? Thanks for chiming in, I can use all the help I can get.
