Trailer Light Connections for Kody Lights
Kody Technologies bike rack lights work with standard trailer connections — whether you have a flat 4-pin or a round 7-blade connector on your vehicle. This guide helps you understand the difference, identify what you have, and get connected.
Check the back of your vehicle near your trailer hitch. You may already be wired and ready to go.
There are several trailer connector types — the most common for cars and SUVs is a flat 4-pin, and for trucks and RVs a round 7-blade. Both work with all Kody lights.
Not sure what you have? See the connector comparison below, check your owner's manual, or contact your dealership.
Tip: Curt Manufacturing has a great reference for all connector types at curtmfg.com.
4-PIN FLAT CONNECTOR
• Standard on most cars and SUVs
• Powers tail lights, brake lights, and turn signals
• Works with all Kody lights
• Best for: standard setups
7-BLADE ROUND CONNECTOR
• Standard on most trucks and RVs
• Powers everything the 4-pin does, plus additional circuits
• Heavier duty cable — no adapters needed
• Enables reverse lights (available on select Medium and Large Kody lights)
• Includes integrated license plate light connection (plate ready)
• Best for: trucks, RVs, or anyone wanting to future-proof their setup
BOTTOM LINE: Both connectors work with every Kody light. Choose 7-blade if your vehicle already has it, or if you'd like to add reverse lights or a lit plate holder later. Look under your rear bumper near your hitch:
• Flat rectangle with 4 holes = 4-pin flat connector
• Round plug with 7 pins = 7-blade connector

If your vehicle doesn't have a trailer connection yet, you have a few options:
1. DIY — Purchase a plug-and-play wire harness made for your specific vehicle from a dealership, auto parts store, or online at Curt or etrailer. Installation is typically very simple.
2. Have it installed — Take your vehicle to a local rack shop, auto shop, or dealership. They can find and install the right harness for you.
We recommend non-sequential lights on Ford (2016+) and Tesla Model Y vehicles due to electrical compatibility. Contact us if you're unsure.
