    Hey guys I just recently added a Westin bumper and a which to my 2.5 Gen and I bought 2 sets of light blocks in replacement for the fog lights. I am currently awaiting a split H11 harness for the lights but noticed that the male end of the blocks pins that plug into the Tundras stock fog light harness seem to be a bit wider than what the original foglight had. It also came to my attention that the sleeve for the male end seems to be too long for the pins to properly seat into the harness which results in not connection. My question is that will the tundras stock wiring harness be able to run 2 lights per harness and if so is there a possibility that the male end they sent is too big for the stock pigtail and will need to be replaced with another?

    Here's a picture of the setup.

    Supplied harness definitely looks off for an H11 plug-in. Factory fog circuit is rated at 15A for both lights, H11s typically run on 20A for each bulb. My suggestion would be to do the math for all 4 LEDs and see if they run less than 10A draw combined. If not, I would not utilize the factory harness. Personally id wire one set to the stock harness and one separately to be able to control each set with a separate switch.

    Edit: Using the factory harness as a dual relay control would be totally fine though.

    The site states 1.6 Amp draw and I'm not sure If that is per block or per set of 2. I'm still juggling with ideas and my original idea wanting to be able to control the light with the foglight switch knowing that with high beams they'd go off which is fine. I'm trying my best avoid any drilling for switches inside the cab. If that's my only option I'll take it, just not preferred.

    I run 4 Rigid pods off of my stock harness and plugs using the factory switch with no problems at all. Your plugs are off because they are not H11. I had to get adaptors for them to work. My truck is a 2020 as well
