Pacesetter Lt's

So I'm lookin at buying the longtubes this weekend, but my only question came in with the wiring. I see wires in the kit for o2 extension, are these for the rear o2 sensors (which I'm getting turned off) or do I need to splice these in/ connect something in to lengthen the front o2 wires?...Tell me your guys experiences! Thanks.

I have the pacesetter lt's and I also got the extension kit, but didn't use it. I can only assume that it lengthens the rear o2's which I have deleted too. I didn't end up splicing anything.

no need to splice or lengthen anything. they work just fine
