Bought the Yamaha Universal Heated Grips and installed on the 2019 MT09. The optional harness made things easy, plugging into the left side off the GW module. Went pretty smooth routing wires to keep it clean, Found out the 2amp "terminal" fuse immediately blows, replaced with 5 amp. The grips aren't as "rubbery" as the original, kinda bummed about that, Looking forward to riding. Got 3" of stinking snow this morning though...maybe tire studs???
