Already have a 30-0333 and want to run dual WB but saw a few posts on EFIlive forum that mentioned the 30-0334 was needed but that might only be for EFIlive.
I can get a good deal on a 30-0333 but want to make sure I can run 2 of them in HPT. If not, what do I need?
EDIT: Can I also connect the second OBDII gauge to the back of the 1st gauge inside my pillar rather than run 2 individual cables to by OBDII port under the dash?
Thanks
