    For all you electrical wizards I have a question,

    I have a Morimoto 40' Light bar that I need to hook up before the weekend. It uses a male 9006 12V connector. I purchased two harnesses cheap off of Amazon, this one(heavy duty and waterproof) and this one(which has the 9006 connector that I need). I also have this switch.

    I have no previous electrical experience but im assuming I will have to splice some wires and jerry rig it together and to be entirely honest I have no idea how to do that. So im looking for some advice and instructions to do this in the safest and most effective way possible.

    If you have any advice please let me know, also if you could list necessary tools and materials that would be great.

    Step 1: If you don't know with 100% certainly what you are doing with an electrical install, THEN DO NOT DO IT. Have a pro, or fellow TW expert, do the install.

    Is your idea to use the Weatherproof harness, but to add that 9006 connector from the other harness to it?


    EDIT:

    I know alot of people are suggesting you take it to a shop, which probably is the safer option if you truly have no idea what your doing. But, with every mod you want to do, I think attempting them yourself is self-satisfying, and if it ever breaks on the trail you will know how to fix (or at least bandaid) untill you get home. I don't think electrical mods are any different.

    The only item that could cause you confusion is the Relay, but it looks like that is already hooked up. You just need to give the harness 12v from your battery (red wire with the inline fuse), ground the black wire to a spot on the chassis, and attach the leads from the relay to the light.

    All it would take is to cut and solder the connectors. Being that you asked the question leads me to believe that you're not comfortable with this. I'd recommend asking a local for help. It's really less than a 1/2 beer job anyway- more of a sip really. Try posting in a regional thread if you want TW help or seek a professional install if you have the $$$.

    But I like electrical fires :D

    Yea essentially, I have a trip I leave for Friday morning that requires the light bar being set up, never made a harness and this was the best thing I could get my hands on in the matter of two days. So I just need to get it working, If it truly is sketchy for me to work on it myself then I guess I will have to seek help but im kind of in a bind.

    I was under the expectation that it was pretty easy to do, but I guess that's only if you have previous experience.

    Everything is easy if you have experience. Nothing wrong with being new at something. I posted in your build with a bit more info.

    If you have a soldering iron, this is really easy. I would stay away from butt connectors for any of your splicing needs. (Reminds me I need to redo my entire bed light harness because I have a fault butt splices)

    Also, those 9006 connectors look cool but will probably add to your confusion. Just go with the HD harness and use a soldering iron to attach the leads from the light bar to the relay.

    If only I had one of those. Cant I just use electrical tape and tape them together o_O

    EDIT: When you refer to the HD harness are you talking about the other one in my possession?

    Don't use tape... Lol

    And yes, I was referring to the 2 harnesses you bought off Amazon.

    It's too short unfortunately. Also have no idea to do with all of these additional connectors.

    This is what I would do. Forget about the second harness for the time being.

    The extra spade connectors from Harness 1 should connect to the female spade ends on the loose wires.

    Go ahead and run the switch through the FW and into your cab. The Red, White, and Black wires from the switch should run right into the relay. Without knowing exactly, White is probably switched power, and red is power. Basically, when you flip the switch it would send 12v to the relay. This 12v from the switch, flips the Relay then sends the 12v from the battery to the light.

    The black and red wires with the ring on them can be connected to Red (Positive) and black (negative) on your battery. This would make your LED bar always hot, meaning you can have light without a key in the ignition.

    I might be making matters more complicated but I purchased a switch and it's wire ends look like this:

    Which will require more sodering to connect wires I'm assuming

    Ah, and yes that's an accurate assumption. I see a R, G, B, and Y wire on that switch.

    There is probably an extra 12v lead for illumination. This is going to get difficult to explain without being there in person lol
