Ive done extensive searches on the header install, but no one has posted anything on the type of wire and guage used to extend the o2 sensors for the gen 2 Tib.
5 stars to the first one to post something good.
Im getting a header, im getting a header.

longuer wires needs larger gauge,i would step up 1 gauge up of the stock wire juste to be sure to not add more resistance in the circuit,but sure to solder and use shrink tubing on every wire you cut
Snow, as far as the first o2 is concerned, if you peel back some of the harness wraping that's on the first sensors. It should reach all the way to where you guys have the hole on the headers, down by where the sway bars are at (or so it was on yuri's). Now the second sensor you should need about maybe 4' of four different colored wires. Now question, the harness that the sensors have, have two wires that run with some insulation, which I believe are the signal wires, would regular heat shrink do for this?

Shoot, I just cheated and used wiring for a stove. You can get it at most appliance stores. 2 wires are wrapped/shielded, and 2 are "alone" the bundle of 4 is wraped in a heat shielding tubing. It comes in 12 and 24" lengths. 12" should be more than enough.

Would it be more efficient to run a slightly larger guage wire from the ECU all the way to the sensors??
like Denisst99 said, longer wires create resistance, so to compensate for length you need diameter, this is true because I learned this in an advanced digital electronics course I took.
