Hi everybody I need some help on wiring Axe mirrors on my 2017 V Rod Muscle.

Standard wires on V Rod are Left Hand  Black with White stripe wire  and Purple wire ...  Right Hand  Side Brown wire and  Black wire.

Mirrors have 3 wire red black and yellow .

Black earth

Red park lights which i wont use.

yellow indicators

I connected as their wiring diagram black to black and yellow to purple but nothing works.

tested new lights on battery they work.

I rang 2 Harley shops one told me to reverse wires as they were LED and are sometimes opposite and the other shop said there should be 3 wires  on the Harley I think he was a bit lost.

Can any body help me on the correct way to wire these in.
