My blower motor on my 2013 FL M2 106 stopped working the other day. I replaced the blower motor and it came with a new wiring harness. The old blower had a fat blue and a fat black (power and ground). And 1 light blue rpm wire. I replaced the control unit in the dash also. I'm getting voltage on the harness but the blower is not coming on. One difference is the new blower has two little blue wires on the back. Rev2 it says. Any idea why the blower won't come on now? I have checked the fuse under the hood and checked the ground
