I’ve put this wiring harness in multiple cars now, and I still can’t get over how cheap it is for what you get. I found it while looking for a budget way to rewire old hot rods, and it’s been one of those buys I keep recommending to anyone doing a street rod build.

Quick verdict
This is a 14-fuse, 12-14 circuit universal harness with real copper GXL wire, a modular flasher, a 40-amp relay, and a cover with a fuse legend — for a fraction of what the big-name kits cost. You get a lot of wire for the money, and since it’s real copper, it’s honestly a steal. It’s not a premium show harness, but for a “hotrod” build where you’re running what you need to run the car plus a basic radio, it’s genuinely great. It’s been on my cars in regular 100-degree desert heat without a problem. check current price on Amazon
Why I bought it
I was wiring up old cars and didn’t want to drop serious money on a name-brand harness when I knew what I actually needed: enough circuits to run the car and a basic radio, nothing more. This kit covers that at a price that made me double-check the listing. I’d also read enough about cheap harnesses using aluminum or thin wire that I wanted something with real copper, and this one is GXL copper throughout.
What it’s like to use
The wire covers are cheap — I’ll say that up front. But as long as you’re running a “hotrod” setup, meaning just what the car needs, it’s fine. The main circuits are 9 feet each, which was enough room in every car I put it in, and the box can be mounted in any position with decent clearance behind it. The modular flasher and 40-amp relay can be moved, which helps when you’re fitting it into an old firewall. I only had to supply a little extra wire for a few things, like the fuel pump — nothing major. My one strong recommendation: use good harness tape. Old cars have sharp edges everywhere, and good tape keeps the wire jacket from getting chewed up if it rubs something. It’s held up perfectly on my cars in the desert, where it’s regularly over 100 degrees.

Who should skip it
If you’re running high-amp accessories — big electric fans, a winch, a serious sound system — this isn’t the box for that. I’d run a separate fuse box for anything high-amp. And if you want a premium harness with heavy-duty wire covers and a show-quality finish, this budget kit isn’t that.
FAQ
Is this wiring harness real copper?
Yes. The listing specs GXL copper wire, and in my experience it’s held up through multiple builds and years of desert heat. For the price, you get a lot of wire and it’s real copper, so it’s a steal compared to premium kits — just tape it well so sharp edges in an old car don’t cut into the jacket.
How many circuits does this harness have?
It’s a 12-14 circuit harness with 14 fuses plus extras, and the main circuits measure 9 feet each. There’s a built-in modular 40-amp horn/acc relay and a modular flasher you can move, plus a heavy-duty diode to prevent run-on with MSD-style ignitions.
Can I run high-amp accessories on it?
I wouldn’t. For anything high-amp, run a separate fuse box. This harness is best for a basic hotrod setup — what the car needs to run plus a basic radio. Keep the load reasonable and it’ll treat you well.
Bottom line
If you’re building a hotrod on a budget and need a solid, real-copper harness that just works, this is hard to beat. It’s cheap, it’s held up in brutal heat, and I’ve used it in multiple cars. Just tape it well and keep high-amp stuff on its own box. check current price on Amazon
