Hi guys,




I was wondering if you could help me.




I bought some Defi garages, oil temp, boost and oil pressure. The problem is as follows.




When the temp gauge is fitted at the front of the engine it works, but when it’s fitted above cylinder 3 it gets no reading. No red flashes or beeps.




I can’t fit both temp and pressure sensors on a T under the alternator because the pressure gauge stops reading and flashes red for some reason.




Spent 2 days on this crap now and getting really fed up.




Any help is appreciated, thank you.
