    Hi all,

    I have searched but could not find any post to help me with my predicament, so I apologize if this has been addressed but I am unable to find it.

    I am a true novice when it comes to wiring, so I am asking for help please.
    I am trying to eliminate large amounts of wires going through the engine bay and still keeping the price reasonable.

    I recently acquired a 32-inch hidden Cali raised light bar for a 21 TRD which has been installed and works when powered up.
    Everything is going through a fuse block connected to a 100amp circuit breaker.

    From the light: I have power going to pin 87
    Negative to pin 85 (coming from fuse block) which is grounded to chassis.
    Power from the battery (coming from fuse block) to pin 30
    Pin 86 goes to the cab switches.

    Inside the cab, I used plug and play switch illumination harness with daisy chains.
    The green is connected to my washer fuse panel through a add a fuse with a 3amp fuse and a the 20amp fuse for the washer fluid.
    The red came from pin 86 from the engine bay.

    Illumination of the switches comes on when vehicle is in accessories mode, but when the switch is pressed, no power to lights bar.

    I set a multimeter to the fuse block and circuit breaker there is power being supplied.
    When I pressed the switch, there was no power being supplied to pin 86 (not sure what to make of this.)

    Any advice on what to do next or what I have missed during this installation would be very grateful.

    I currently do not have any pictures at the moment so sorry about that.

    Thank you in advance!

    Not sure how their PnP harnesses are wired, but I know lots of people have issues with them. However, your wipers should only work in the ignition ON position. So that would explain why they don't work in ACC.
    I would suggest that you install a Bussmann RTMR if you want a clean look and waterproof setup.

    I have followed the instructions to the "T," but still switch lights up, but nothing up front from the lights.
    disconnected straight to battery and light bar still functions. I needed to check for sanity reasons...
    Am I missing something somewhere?
    I also made sure the truck was in ignition mode and still nothing.
    Relays are clicking, have switched out to brand new relays just incase and still nothing.

    Can you please take some picks of how it’s wired. Because something is definitely not right.

    Keep it simple. Trace the circuits.

    Relay power:
    add-a-fuse - switch - 86/85 - ground.

    Main Circuit:
    Batt - Fuse - 30/87 - lights - ground.

    This community rocks!!

    Thank you all so very much for the awesome help!...
    After retracing each wire, and testing each wire it turned out, (crimping skills sucks!).
    I had to order some new crimps, and such so will finish the rest when all the products come in.


    I will be posting pictures when it's all done, Again, thank you all for the help!!!

    @Phlogiston, I actually finished it a while ago, I just got so busy that I forgot to post it up until I was searching for something a few weeks ago. Then I remembered, but better late than never.
    Yet again, I do apologize for the lateness, tardiness, absents or whatever you would like to call it.
