    Hi Guys.

    Is there any diagram over the pins of the Ecu for 1992 E36 ? (325i in my case).

    Wanna install an Oilt Emp gauge + Water temp gauge and I wanna connect to Ecu instead of going for the sensors directly.
    Ecu it's a BOSCH 402

    Thx in advance.

    You won't have an oil temp gauge fitted, if you need something for that, you'll need an oil pressure adaptor and screw a temp sensor into it instead of pressure.
    And if you've gone that far, you might as well just use an actual oil pressure gauge, which is more useful.
    All it'll have at the moment is an oil pressure switch, which is FA use to anyone, as it'll only warn you that your oil pressure is so bad, you shouldn't be idling, let alone driving!

    For coolant temp,

    It's over pins 43 and 78

    Thx again
    Damn that manual is big....
    K , so if I wanna fit an oil pressure gauge , i guess there is a pin on the cluster also ? Or should I go also directly to Ecu ? What I could find in the manual it was a pressure SWITCH .. no sensor.

    You'd need to buy an actual oil pressure sensor, and the adaptor, and wire this directly to the gauge.
    You oil pressure switch comes out, it's behind the oil filter
    you screw this in
    http://cgi.ebay.co.uk/BMW-E30-E36-32...#ht_1806wt_704

    Put your press. switch in the back and screw in an oil pressure gauge into the side
    http://cgi.ebay.co.uk/UNIVERSAL-SEND...ht_2427wt_1025

    Keep an eye on getting the right threads, RealOEM tends to list thread sizes next to the parts for help.

    That then goes straight to the gauge.
