This video should have been named 'how to REPLACE' a 7pin plug.

You have 1,000,000 videos, why not add the url link to the viseo discription of the video where you mention wirongnfrom scratch?

Can we just stop and appreciate that this channel has 61 THOUSAND videos uploaded!? That’s insane. Just today there was like 300 uploaded, how is that even possible. Kudos to the determination lol. Also good video haha.

PERFECT DIRECTIONS

Excellent video, short to the point and very informative, thanks 😊
-
where can I Find the plug combo kit that has all wires on one end I've been researching it and cant find a single one
-
What I find confusing is when a blue wire is for "brakes". But, the brakes use the left and right turn signal wires, and I think a higher voltage on that wire, brightens the output of the bulb when you hit the brakes. So, what does the "stop" wire do? Is that for electric brakes, and the signal causes the brakes to engage?

where did you get that light tester with probe guard? ?

If you use a 4 flat to 7 blade adapter, do the brakes, backup light, and 12 volt work, or are you missing out on that functionality? I'm deciding if I need to take out my 4 flat and replace with 7 blade or if the adapter would accomplish everything. I just got an RV to tow and am having trouble figuring out why the brake and turn signals are not working. I am using an adapter. Going to test a few things tomorrow with the trailer plug, and the truck itself. Thanks

My car trailer new / has 2 black wires No blue wire ? Has battery on trailer
-
your wire tester looks pretty awesome. Does it poke thru the insulation or work like and A/C testor which just senses the voltage?
-
Need to update your video description. The link for shopping 7-way...doesn't work.

Question about the red wire/brake wire. I have an existing four pin working in place. Bought the four to seven adapter for my new trailer. Do I need to connect the red wire brake to the controller? Is it redundant? Or does the red wire feed to the brake controller tell it to activate? I would prefer to skip the red wire, can I simply provide 12v 20amp to controller under dash and send the blue wire to the seven pin? Trailer has no reverse lights and I am not adding them.

where is the vid to wire it from scratch??? I just used a pre existing plug on a new used truck i just purchased. A 2000 freightliner fld120. My issue is that everything works but it has no brake lights. Everything on the truck works fine and I ran a test light on the ground at the pre existing plug and it seems fine. Blinkers work fine but no brake lights. Cant figure it out.

What harness are you using in this video? It's exactly what I need to replace my old damaged 7 way, but I can't find it on the website and there's no link in the description.
-
At about 1:40 into this video, you mention a video about wiring from scratch. I looked for it but can't find it. Can you post direct link to that specific video?
-
Can you share the link for the wire tester
-
Where is the link for wiring vehicle from scratch mentioned in this video? I want to wire a 7 pin for a 98 Durango
