Ok I'm not a stupid as I thought I was, haha. I could not for the life of me put this plug together. After looking at the connector, like was sent to me with the engine, for sale on Leading Edge airfoils, I got the wrong pins sent to me. The pins sent with my 881302 connector are for the 881300 connector. I can't find the pins I need so I ordered a new plug for 40 bucks.
I have called and emailed the factory for a pinout on the pressure sensor 10 pressure sensor that they sell you when you buy the engine but haven't found anyone that knows.
The other fuel sensors all seem to have the same pin outs so I hope this one does too cause that's the way I will wire it.
I did join the rotax owners site and got pin outs for other sensors but not the pressure sensor 10.
