    Does the oil pressure sender you want have 4 prongs for the wire connection? I have one of those that I believe works. Would have used it myself, but don't have the wire plug for it. JImChuk

    The new Rotax ones are variable current (mA) output, 3 wires, and are incompatible with certain older gauges. The VDO style are variable resistance with 2 wires.

    I found it while looking for something else... I can't make out the part number cause the label is mostly gone, but here are a couple of pics of it. JImChuk

    Looks like the earlier style like I have on my model 4. Donít know if it will work or not?
    I ended up getting one off eBay with the harness. Thanks for looking though.

    I'm in the process of wiring up my MGL E1 engine monitor at the moment. I bought a Swift oil pressure sender from Aircraft spruce for the 912, and can't figure out how to program it to the engine monitor. If I knew what the 4 terminals did on my Rotax sender, I would try to jury rig a plug to fit it and put it to use. Any ideas anyone? Thanks, JImChuk

    Hi Jim, Iím looking for a transducer like the one you have. I believe it is Honeywell part number 9306103 or Newark Part Number 62M8673. 4 wires with a tapered thread. Please let me know if you still have it. I sent you a PM but not sure you received it?

    Thanks

    John
