FARBIN Horn Wiring Harness Relay for Car Truck 80A 4pin Spst Normally Open

Bought this for a Hella horn setup on a Gen 11 Honda Civic. I did use the relay that came with the Hella horns but the clear relay that it came with the harness looked solid. I do wish the horn trigger wires were a bit longer for my setup but I made it work. Overall I would buy it again

Works like a charm, easy to install. horn power and ground leads are very short, so the relay must be mounted within a few inches of the horn. For me that means above the radiator where it will be exposed to rain and dust. Time will tell how well it holds up, but for now it's certainly worth the $10 I paid for it.

Easy instal self explanatory

I bought 2 harnesses, and they worked well until they didn't. About a year later, both sets stopped working. The wires had corroded on the inside of the cable and couldn't carry current the 2 running theories are 1. the wires were stored improperly, and 2. soap from the car wash (some are known to be able to cause corrosion to exposed electrical work) hit either the relay or an exposed connection. We'll never know but these $10 harnesses have cost me ~$300 to do it right, thanks to paying a shop and now rebuilding it correctly. Don't buy this, buy some wire, open barrel connectors, a soldering iron, heat shrink, relay, connectors, etc. and you'll have a bulletproof harness exactly the length you need it to be for ~$75, less if you have access to the tools. ------------------------------------------------------------------------------------------------------- It took me way to long to find out the wire going to the stock horn was positive and needed to be connected to the blue wire. The white wire needed to be grounded (which was unclear for me.) The white wire is a flat blade which may need to be replaced with a ring to ground to a screw. Also the leads are only ~6" so be prepared to make extension cables if your horns are spaced out. Instructions are garbage, but some how still better than Hella's. Other than that it was easy peasy.

I also ordered a pair of their high and low tone horns with this harness. Installation will vary depending on the vehicle you own. Mine was for a 68 Pontiac GTO. I listened to the horns from their ad and liked the sound. They did not disappoint. I wanted that big GM car sound of the 60's. Be prepared to have some additional same gauge wiring and connecters on hand as I had to lengthen the harness for my application. I purchased a horn button from a local auto parts store which came with it's own wiring. Take your time, the instruction diagram is easy to follow and is in color. I'm a happy camper!

Nice and loud, exactly what I was looking for to replace the stock horns in my Nissan

Absolutely a HORRIBLE design. Anyone that knows anything about electrical knows 16 gauge (16AWG) stranded cable cannot hold 30A of current. The fact that they have a 30 amp fuse is absolutely ridiculous and can cause a fire. The fuse should be at the absolute max 15A and should honestly be closer to a 10A fuse. So your cable would start to melt before your fuse pops which is a major fire concern. The wire should be swapped for 12 gauge or the fuse should be swapped to a 15A rating. The power cable is also way too short.

This harness made installing the dual horns on my motorcycle a breeze. Instructions were easy to follow. Had the horns already mounted and took about an hour to properly tuck wires out of sight. Connections were easy to make. Definitely recommend this to anyone who wants to switch to a dual horn set-up.
