Great job on video! Very thorough! I have a 21 at4 and I’m wondering if this switch will work in my truck. I’m getting so many different answers. I just want to get the customization done on my truck. Our trucks do look so similar.
Awesome job on the series, I just ordered my parts today. Thank you for the part numbers as my dealership told me that it wasn't available for my truck, but when I gave them the numbers they couldn't argue it. I applaud you for your attention to details and explaining everything. This is extremely helpful.
If you don’t have a factory brake control can you still use this switch kit?? Tjanks
Awesome video. Do you has the link to order all of this? Thanks for the video best one out there for this upgrade!
Like how you walked through the steps and had good camera angles. Nice Work!
Great tutorial man! Thanks a lot!
I tried looking up the part numbers and was able to find everything except for the Block Kit, apparently it’s discontinued. Do you know why? And do you have suggestions for an alternative?
You don’t need to take half the dash apart to install the switch harness. Just pull the screw clips off the fuse box on the harness and put 2 short bolts in and lock washer and bolt it in instead of the stupid screws took like 30 min to do the whole install start to finish
Don't cut that green with blue tracer wire!!!!!!! This goes to the connector under the headliner for another Aux light. it's already hooked up.
This was aLOT OF HELP!!
THANKS!!
So.. now I have the switches installed.. nothing hooked to them, but testing with a test light.
Brings a question.
Are these switches all hot with the key off?
Do I have to run the power through the firewall just to power switch 5 for the roof beacon? Or can I just plug into the terminal and use the provided fuse block and only use switch 5?
you should use a fuse on the amp cable close to the battery, besides that's great set of videos
Great video, I will be installing mine this weekend. What are you using your switches for?
no fuse on that amp wire???
What size wire loom did you use? I want a clean look like yours?
THANK YOU VERY VERY MUCH
Thank you for making this. Very helpful. Man im going to be doing this on a 2500, ima gonna have to crawl inside the engine bay to get to that rubber nipple. Haha
