Hi everyone I'm new to the forum and just purchased a giant full E+1 before charismas and I've installed a Air Zound horn kick stand, water bottle cages and mirror and Ive gone tubeless. I now want to fix lights but I'm a bit confused about the wiring. On my model I understand it that there is a wire to fix lights behind the rubber grommet on the frame. I contacted my dealer and he said it was 6 to 12 volts. I've got a 12v rear light and tried to wire it in but its not working but it works when I hook it up to a car battery. So now I don't know if the wiring to the bike battery is hooked up or its not 12v. Can anyone give me any info I tried ringing giant twice but both times they couldn't tell me anything and I cant find any info anywhere
