Fast window mod - motor relays on a PCB!

I replaced my old, original, channels when I had the door card off. I took the window out too bc the bottom metal channel attached to the regulator had come off both rear doors so the windows weren’t working at all (this was a recent issue w/ the one). Both rear windows are now operating like a new vehicle and my dogs appreciate it greatly. One caution: if removing your windows be VERY careful with the divider bw the main and fixed windows when putting it back together if you have tint. It WILL scratch your tint if you’re not very careful (and might even if you are). Ask me how I know!

Not yet. I'm lagging. Just busy :(
But it is on my list! Hope to have something out this week
this is what i put together during the video to use when I wired them:

window mod wiring:

◦ red on board goes to blue tying it in both sides. your power.
◦ white on board to red/yellow switch side
◦ blue on board to green/yellow switch side
◦ green on board to red/yellow on connector side
◦ yellow on board goes to green/yellow on connector side

Is this correct?
Just checking, as it's what I got from the video as well. Don't wanna hurt em on accident!

Thank you.
 
Hi all - here is a basic wiring diagram. Will upload to the site as well.

Made a splice harness. I assumed the unlisted green-blue and red-blue were just straight pass throughs.
Still need to figure out a good ground spot

awesome! Planning to make a few of these available as well soon.
 
Splice harness worked great. Grounded to a little 6mm bolt on the door panel. I added some protective sheathing to the ground wire since it’s floating around sheet metal edges. So far so good. Two more doors to go.
 
All 3 units crimped in place / installed with minimal issues. They work GREAT!

(Don't take apart a back a row window switch to fit it through the door card after crimping, at sunset, in the yard/dirt. You'll be sifting yard dirt in the dark with a headlamp to find the guts of the switch that boinged everywhere to repair the switch to get the window up before it rains...
Still didn't find 1 part, I think the chickens got it, had to raid parts from a switch doctor switch.)

Other than that, I found a great improvement on window speed with these, coupled with new window runs. Speed is improved from the individual doors AND from the master switch on the drivers door.

I had a chill afternoon in crimping mode with music playing in the background. I had fun.

(The wire harness "plug and play" option would be worth it, in my post crimping opinion. Will make life much easier for any future door card removal for service.)

Very pleased.
Thank you for putting energy into a solution like this!

Awesome to hear!
I agree - will get a plug and play option out in the next few weeks. Small batch to start to gauge interest.

I originally designed this for myself and my vehicle had the previous owner's hacky wiring job in there, so true plug and play was never an option for me and I hadn't thought of it until you all suggested it! Great call-out
 
Is it suppose to do this @jonnyd42? Went down fine. Not coming up. Worked once at the shop when installed. Not functioning now.

Hey! If you're in the bay area CA, I can help debug this in person. Otherwise please double check the wiring and if that looks good I can just send you a replacement tested board. Do the other windows work fine?

Hey, sorry had an emergency come up I haven’t been on here and the truck is back at the shop until the end of the month. Will reconnect when its back.
 
Finally installing mine today. Also doing sound remediation on the doors since I have the door card off. The wiring was easy just followed the video for wire colors.

Nice! How do they work?

Its still torn apart. Had to go out of town for work this week. I will get it back together this weekend. I was waiting for new 3m butyl rope to put new vapor barrier on the doors. Also shampooed and cleaned the door cards so they are drying. I did do a before video on window speed so I will do an after video once installed.
 
Finally got my windows buttoned up and reinstalled. Since it was torn apart I put sound proofing in and new vapor barrier and shampooed the door cards. It is faster. Mine worked pretty well originally but the rear windows are definately faster. One side note I wrapped the circuit boards in electrical tape as I installed one side and they contacted metal and shorted my relay out. Just had to use a paper clip and reset it on the top near the fuse panel. I also taped the circuit boards in place against the vapor barrier and door card so no where near metal.
