If you need a quick and simple way to wire a pair of Hella horns, here you go!



OLM Hella Horn Harness V2

This simple harness plugs into your factory wiring and gives you a couple sets of outputs you can connect directly to a pair of hella horns. As seen in the picture there are two locations where this can plug in usually. Earlier model years can use the driver's side horn plug with this cable.

NOTE: On newer models, you may only be able to plug it into the "F5" connector. You'll notice that your driver's side plug only has one prong and uses the bolt holding the horn in for the ground. Trace the wire back from the PASSENGER side horn until you see a plug that fits this product. It is located on the main front harness that also leads out to the headlights.

NOTE 2: Be sure to hold the wires by the base and make sure they are aligned as you connect the male and female connectors. Once you have plugged it in, use the supplied heat shrink over the connection to hold it snug.

FR-S / 86 / BRZ owners, connect to the high side horn connector which is on the passenger (right) side.

Connect one pair of shorter wires to one horn and a pair of longer wires to the other. That's it!


In one picture below, the harness is showed connected to the OEM connector. The other shows the OEM connector on the left and the OLM harness connector on the right.

Use the heatshrink over the supplied harness connector and the OEM connector.
