I came across an EPS unit out of a 2012 XP900LE and wanted to install it into my ’12 XP900. Found out the hard way that my standard model isn’t pre-wired as the ’11s are. 🙁 I also included part of the harness from the LE for both power and ECU connections.

I understand that there is a small jumper that goes from the diag port to the EPS unit (Polaris 2411648) – but its $170. A bit much for a small wiring harness IMO. Being that I also have part of the old wiring, can I simply make my own harness? I found the type of plug thats used (Delphi 15326840) – I just need the proper pin-out.

Has anyone done this before? Or is there more to this harness than I think?
