This could change based upon where you buy your switchbacks and resistors. I went with JDM Astar LED switchbacks from Amazon. I originally bought some $15 ebay switchbacks but one actually burnt out and the connectors broke off. Buy reputable bulbs!!!

Amazon.com: JDM ASTAR Extremely Bright PX Chipsets White/Yellow 7441 7443 7444 Switchback LED Bulbs For Turn Signal Lights(Brightest Switchback bulb in the market): Automotive


The actual install was quite easy. The more difficult portion was me having larger hands and not quite the space to work in.

1. Underneath the high beam bulb, is your turn signal:


2. Quarter turn, counter clockwise, pull bulb out. Replace with LED switchback.


3. The hard part: Adding your resistors!!! You need to figure out which black wire is the positive turn signal wire. You'll see a yellow wire (ground) all the way to the left of the connector and then three black wires. I've already voltage metered this and I'm going to assume all trucks have been wired the same way but PLEASE double check on your own so you don't end up cutting or tapping into the wrong wire. You'll see here the turn signal positive is directly ACROSS from the yellow ground wire.


4. This means the corresponding positive wire would be the black wire closest to the yellow ground wire. You can hard wire or splice or however you want to connect the resistors to the turn signal wires. I chose to T-Tap.


5. Reinstall bulb into housing and find someplace to mount resistor. I just zip tied the resistor to another section of wires so it's hanging losely. Not a lot of weight to the resistor so no worries in damaging the wires.

6. Turn on your lights and test them out.
