Would be very interested in exactly how you did this. How do you isolate an O2
sensor? They emit a (very small) voltage signal, referenced to chassis ground,
and I was told by K&N tech support that their indicators absolutely would not
work on +gnd, because of their input polarity (isolation or no).

You can use it on + ground cars with no problem. Just have to isolate it from
the chassis. My car is also + ground.
BTW it may be good to point out, that there are two different types of O2
sensors awailable. The wideband and the narrow band. Though the narrow band may
be usefull as a controll device, it is not particulary usefull when setting up
an engine. Esp. if the negine is nonstandard.

Unfortunately, no help for us with 'pure' British essence: positive ground
(yes, I know some 'Merkin cars were +gnd, too).

I mounted two O2 sensors on the downpipes with a dash switch between the two.
I agree this is the best way to go because you can watch each carb's mixture
while driving.
Note - you don't have to buy their O2 sensors - any single wire sensor will do.
