It's pretty easy to figure out how to run the wiring harness I have never installed a whole harness before but with all the paperwork that they give you with the kit they even tell you what conters to use and where they go and how to get started it went fairly well I would recommend the wiring harness to anyone thanks for getting me back on the road after all iam bye no means a fair weather biker ride on my brother's

Bought for rewiring my 78 ironhead- wish i had found this sooner! made wiring a breeze. didnt have instructions, but digital pdf is available here on JP, once i found that it was easy going. not a fan if the included multilock connectors, wound up replacing with additional deutsch connectors, but everything that you need is there (minus crimpers). would definitely buy again
