Turn the truck on. With head lights OFF, you should have one of the wires active. Label this one as your 12V power, it will be connected to the black wire on the 7-Way. Turn on the truck head lights. The circuit that is now active is your running lights, and should be connected to the brown wire on the 7-Way. Turn on the left blinker, identify this wire and connect it to the yellow wire on the 7-Way. Turn on the right blinker and connect this wire to the green wire. The white wire gets grounded to a clean metal area of the truck frame.

At this point you will have 2 wires left on the truck and 2 on the connector. One should be for reverse lights, the other for the brake controller. Have someone put the truck in reverse while applying the foot brake. The emergency brake should also be activated. Identify which wire is hot, and that would be the reverse wire and should be connected to the purple lead on the 7-Way. The last lead should be for the brake controller and should be connected to the blue lead on the 7-Way. — Preceding unsigned comment added by 73.46.75.48 (talk) 15:43, 29 May 2016 (UTC)

7 Wire Blade images are incorrect. This image matches what I test with actually 7 Blade to 4 Flat adapters: http://www.pirate4x4.com/tech/billavista/Chevy/tech/Prodigy/images/7-way.jpg
