![]() I run the bare minimum - the stock Subaru oil pressure sensor goes straight to the VW speedometer oil pressure light. The alternator runs to the VW speedometer alternator light. That is all I have... Oh the gas gauge works too. When tuning, I have the laptop hooked up so I can see RPM, coolant temp, etc. My gauges have been on hold while trying to get the motor set up right. I'm torn between added a lot of gauges to the dash versus putting a small PC in the buggy and using an LCD screen on the dash... I do have a boost gauge waiting for installation. If I remember correctly, I had 2 sensors on the coolant manifold. One I use for the coolant temperature. The other may be for an idiot light, but I have not experimented with it. Any guesses if it is for an idiot light? I suppose I'd have to remove it to test it with some boiling water to see how it functions? Paul...

EMPI Imp 1002 ('69)/Subaru EJ20 Turbo/LinkPlus ECU ![]() I know VDO has a combo oil pressure and idiot light sender, but don't think Autometer has a combo sender? I may have to tap into the oiling system somewhere to add a light for this. As for the cooling sensor, I tested the original sensor on my JDM engine and it had similar response to a Bosch temp sensor - I've got the notes in my Megasquirt file and can look them up if you need the details. I don't think this would work as a light on-off sensor though, it has a linear resistance curve based on temperature. I can't recall if my manifold had 2 temperature senders or not - I think it did? I do recall multiple openings in the manifold, one of which I re-tapped for an Autometer temperature sender (standard NPT). IIRC, I think I read somewhere Subaru used 2 temp. senders, one for the computer the other for a gauge? I'm using that (separate senders) layout on my engine, FWIW. What I'd like to run is gauges for (water) temperature and oil pressure, plus a large light for oil pressure. I think my overall gauge layout will be tach, speedo, oil pressure, water temp., boost gauge and fuel level gauge. I prefer analog gauges for all this and planning to install Autometer gauges. Jeff ![]() I do like the look of the analog gauges. Trying to get to the back side of them with an Imp dash is a real pain... I need to be better about building harnesses for each gauge so I can unplug the harness and pull it through the dash. Paul...
