Hi volks

I replaced my completely rusted out exhaust system today with an S&S
header (more later) and installed a new o2 sensor since the one that was
in the rusted piping was rusted in solid and broken off. When I bought
my van (85 GL 1.9) there was a new o2 sensor in the glove box so I put
it in today. It is a universal design bosch with 1 wire. Now from above
I can see a bright green wire with a black male spade connector, but
from below by the sensor location there Is a harness with 2 wires that
are cut one brown and one green/brown. Which one do I hook the o2 sensor
to and is a 1 wire sensor the right one?

 

The S&S header went in absolutely perfect with no fitment issues. I took
me an hour to get the old out, an hour to remove all the old studs and
30-45 minutes to install the header with all new studs and nuts.

 

Any help with the o2 sensor wiring would be greatly appreciated.

While I was working on it I met a guy with an 80 westy and his sits way
lower to the ground than mine. He asked if mine was a Syncro because of
my new 27x8.5R14s look so big on it.
