Wiring Resistors In for Switchbacks in 2011 GMC.

I've purchased 4 V-LEDs 5000k switchbacks with four 6 ohm resistors. And the resistors are not colored as in negative or positive. So I'm assuming it doesn't matter.

Here is the diagram I'm working with and how I'm palling on wiring:



But some are saying that way is working and some are saying it isn't.

So could someone tell me the best way to wire in the resistors with the least amount if trouble?

And if anyone has any tips on mounting them that would help.

And I plan on using the piggy back scotch lock connectors. If there is something better let me me know please.

The truck is a 2011 Sierra SLT.

Thanks in advance.

Edit: Okay my headlight a are different. There's no wires coming between the too and bottom like the diagram I posted. And the bottom light has 2 green wires and the top has 2 brown wires. Help please.

Got them in. Working like a charm. I only had to use 1 6 ohm resistor per side. But they are working perfect. No hyper flash

Austin how did you end up wiring your resistors I have the same head lamp wiring and did something wrong

Between the plug and where the harness "T's" off all of the signal bulbs, tap your resistor into the brown and black wires.

Wire the resistor before the “T”?

The harness splits off after the plug to the running/signal bulbs. You could effectively apply a load to both bulb circuits if you splice into the harness before the wires split off to the individual bulbs.
