Old Saab 9-3 2.2 TiD - Adding extra gauges - braniff7
Thinking of adding water temp (the existing is not direct reading), oil pressure, oil temp and boost pressure, on "A" pillar housing(s). Yes, it's a strange choice of car, let's say it's a practise run....

Where best to insert the senders/sensors, either specific to this engine should anyone reading this be familiar with it, and are there any senders already extant which could be exploited/piggy-backed (I assume the ECU receives some of those values anyway).

Many thanks - braniff7
