Been doing a lot of reading about the H4 harness upgrade and I want to look into building my own harness since I'm handy like that and I want something to do while I'm sitting and watching football and drinking beer. I can't seem to find a thread on how to build your own harness anywhere. Can someone point me to a place to for this? If one exists? Thanks

So of all the talk about H4 harness replace, build, upgrade etc .. there isn't one on this website? Weird.

 

Not really. Most folks just buy them. I've installed at least 12 of them with no issues.

 

Yeah I see the convenience of buying them, and I certainly trust buying them. Just found it odd there wasn't a "build your own" topic. I did see a dude on a website that said it's easier to buy rather than build cost wise. Not saving much by making your own after you save time buying them.

 

The one I use is listed/linked on my website in the Tip for installing one.

 

Wow...... $18!!! Not bad at all!!!!!!

 

No need for an expensive harness. Except of course, bragging rights.

2 things to be aware of upon installation. FASTEN the relays. Don't let them bounce around. Also, mount them so their blades face DOWN.

Where the grounds go, scrape to bare metal.

 

Ordered!
