I just got my gauge and read the intructions, it says to join into the O2 sensor on the exhuast, ive read on this ppl splicing into the ECU end, what would be best? also ppl saying there connecting to there lambda sensor instead, soo what would be the best i have a 05 wrx.

Just use the corresponding pin on the ECU, that way you do not have to run wires from outside to inside, and also don't have to solder wires on the outside of the car, where they will be exposed to the weather and other things

Ive had a few in the past on previous cars, and ive always connected mine to the lamba sensor. just chop into the wire already there
