*Your truck must be pre-wired for the Y-Adapter to provide power to your Bed Lighting. All trucks have the connector present, but not all trucks are pre-wired. To determine if your truck is pre-wired, check the C431 inline connector shown in our instruction manual and YouTube installation video. On at least one of the plugs, the following wires should be present:
2015-2017 = Pin #6 (Black with Yellow Stripe) and Pin #7 (Purple) – Please note, there is a Brown wire with Purple stripe that looks similar.
2018-2020 = Pin #6 (Black with Yellow Stripe) and Pin #7 (White with Green Stripe) – Please note, there are TWO White with Green wires on one side. You must have BOTH.
If they are not, you will also need Starkey #4572 Power Extension Wiring
**In rare instances, some 2015 & 2020 trucks may have a black connector in place of the normal connector shown. This product will work with minor modification – see instruction manual for details.
