Rear O2 Sensor
Anybody have details on how to manually resistor one? I have a couple people asking, and I just got mine plug in with a kit. Or where can you buy one thats made for the WRX that plugs in without buying the entire exhaust kit.

you solder a 2.2k ohm resistor in the signal line to the pcm...from the rear o2. drops the voltage to the correct signal...if i remember correctly.
dont remember which is the signal wire color...white i think.

Hey Joey,

Think you can give me a hand some time on the Trouble Shooting Guide? The mod guide needs a few more revisions today before going live; and I have 5000+ receipts on the floor beside me I'm working on sorting for taxes, so it will be this afternoon guys; QUIT IM'ing ME FOR IT!....

Sorry just venting =P
