Hi Scott.
3rd relay is for the HO2S (heated O2 sensor)
The Jetta uses a fancy schmansy O2 sensor with a heater element.
Thanks for the confirmation and tips.
Unfortunately I didn't keep the "high voltage" box from donor. Sold it
with engine. Luckily I had the sense to keep the black junction box
from WBX donor. It looks like it seals properly. Should suffice for
relays.
Neil.
