Fortunately it is complete so will change it over and see if it works!Unfortunately not all sellers supply the loom. In my opinion that is bad practice and the wheel should be complete and ready to go.
Simon perhaps get an SE wheel airbag loom unless you have one already on your spare SE wheel.
Any pics?I fitted TT wheel, love it!
Tbh i found alighning the splines a touch vague and had to have another try as first time was a spline out which really upset my mojo!
