915is fuel pressure plug pin out

[Kitfox Pilot]

Can anyone tell me the pinout of the plug in the first pic and where to connect the wires to on the ems? I can find bits and pieces on the rotax owner support but I'm not a member to get any access to any diagrams.
I can't even figure how to put the pins in the plug....I'm sure its easy.....
Thanks for any help!

I believe the fuel pump wiring is discussed in this manual:

Hi Gary, I got the new end from LEAF today and it took 10 mins to wire everything when you get the right ends. Same ziplock package and no instructions in it either. Glad Brett gave me all
that info a couple days ago.

I wouldn't encourage anyone on an engine choice. Which ever one someone chooses is fine with me.

Glad you got it figured out Harlan and I wish more people were open to other people’s engine choices as you stated. We are building these things to satisfy “ourselves”..

Fuel pumps are wired and work fine.
I am working on the fuel pressure sensor and it seems to be a mystery.
No one at the factory today that knew the answer. I have an email in to John but he was out today when I called.
Every Rotax IS engine has this on it so someone knows....

Thanks for the link, I have been through that book already but I missed it if its there.

I also see that I misread your post, entirely. Sorry about that.

No problem Mike, I'm sure I'm overlooking something on this simple wiring job.

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.

Frustrating trying to figure things out when its part that are defective or wrong part numbers!

Yes it does put a different turn on things. Brett from Leading edge airfoils found the pinout in the rotax heavy maintenance manual for me. Thank you Brett!
