I ordered the Symtec heat demon's from calsporttouring. they were on backorder when i ordered and it took a month to get them, they don't inform you so beware.
Next i followed the instructions of installation. I cleaned off my bars really well, when i removed my old grips, i just used soap, so i just washed that off, then i used Goof-off, to get the rest of the glue off using a wire brush, next was to use rubbing alcohol to clean them so you know you will have good adheason.
I have heard mixed reviews but i went ahead and used epoxy to glue the heat elements to the bars, you don't want that spinning after a month of using it. Next i made sure i had enough slack and made holes in my switches to hide the wires and give it a clean look. I installed the grips over the heating elements, this is used black RTV (its rated up to 500F) and you only need a small amount on the inside of the grip, make sure to wipe the excess off as well.
Then i proceded to wire in the heated grips. This I followed making a Relay method. without a distribution block. I will write down what i used:
1) 5 pin 12V 30A relay, I got this at an electronic store, don't goto the auto parts store, its too much of a hassle and you'll end up paying out the ass, it was $3.78
2) 5 pin connector, it was only another $3.78, and was nice because you can just unplug the relay and not have loose wires and looks more factory.
3) shrink tubing
4) soldiering iron and such
5) volt meter
6) 3 different colored wires (1 blue 18g, 1 black 16g, 1 red 16g) got these also from the electronics place for $0.10-$0.15 a foot.
7) 20 amp inline fuse for the power, just to be safe
And got my "control" wire from the licence plate light, after that it just took time to hide the wiring, but its the best thing ever with the heated grips, i would say that overall, the wiring and relay and everything was $15 and i would recommend because its a safer way to wire your bike without anything "going out" or the bike not starting. I will post pictures soon
