DIY: LED DRL/Turn Signal with resistor install

This install was completed on my 2012 2nd Gen Tundra. Install will be similar for the 3rd Gen Tundras but i dont have confirmation the wire colors are the same.

LEDs purchased from csjumper2003 on TacomaWorld.com. Here is his vendor page: https://www.tacomaworld.com/forums/jumpers-leds.171/

This kit includes:
(2) 4157NA LEDs
(2) resistors with male connectors installed
(4) t-tap connectors
(4) self tapping screws




Comparison between stock 4157NA bulb and new LED



Diagram i found online for the resister install. Will be a little different on the Tundra as the wire colors are different. There is a ground wire, DRL wire and turn signal wire. It is very important to find the correct wires. If you tie the resistor into the DRL wire then the power will be running through the resistor all the time and it will get very hot and possibly fail or cause damage.



The correct wires to tie into on the passenger side are the pink wire and the white wire with black line. Use the provided T-tap connectors to splice into these wires and connect the resistors.



The correct wires to tie into on the drivers side are the red wire and the white wire with black line.Use the provided T-tap connectorsto splice into these wires and connect the resistors.

LED DRL



Resistors installed using the provided self tapping screws. Just find a good spot on the metal to install them where the resistor is not touching wiring or plastic.




The stock bulb is on the left. The new LED is on the right ~5' away from the wall.

If you do not have the kit as described above then you will need the following items
(2) 4157NA LEDs
(2) resistors
(4) t-tap connectors and (4) male connectors of same size. Size is indicated by color. The correct color would be blue.

(4) self tapping screws
