i have a '99 prelude base and was wondering if anyone knew the wiring for the first o2 sensor. im installing a AFR guage and need the wiring designations and colors. on my sensor there are 2 white wires, 1 black (i assume ground) and 1 grey. any help here would be greatly appreciated. *edit* ive read the other post about this, but, mine has 2 SOLID white wires, no black stripe on either one.
