I just got my Orbital Kit and need to move the stock MR gauges. I am thinking of using the A-pillar pod kit available on lancershop. The oil temperature gauge in the stock kit is displayed in celsius, but I noticed that most, if not all, the aftermarket gauges are displayed in fahrenheit. How is this conversion done? If I just connect the aftermarket gauge to the wires of the stock ones, will it give the correct reading?

This question also applies to the boost gauge. KPA vs PSI.
