How To: Wire a Universal Turn Signal Switch... Especially When Using the Speedway Wiring Harness!

[@BarbZurawski]

Great Video !! ...Thanks so much !...I just installed a very similar Switch to my 1929 Model A Pickup ...The instructions that came with the switch were a joke ! ...I followed your instructions and it worked out Great !

[@BadHombreGarage]

Great! I’m glad this helped! This is exactly why I made this video.

Hilarious, it took me much research 6 months ago when I finally figured this wiring out for my Yankee Turnflex switch. to come across this now makes me chuckle as cripes I could have used this then! Getting ready to do another vintage intstall of a vintage switch so this is perfect timing to remind me of what I found out then. Thanks much!

Great video. My Dad use to wire in these universal turn signal switches back in the day. Last one he did was a '53 GMC. Brought back memories. Thanks for sharing. Take care, Ed.

[@michelsmith5610]

It would be great if you could do a video on hooking up cornering lights to one of those switches, thank you

[@BadHombreGarage]

Good idea! By cornering lights, do you mean side markers? I would think you would wire the switch the same; I thought the side markers jumped off the park light and / or turn signal light wires.

[@michelsmith5610]

No , some of these old Chyslers Hava a clear light and a blinker light and a marker light, I can get everything else working except the corner ing lights, they come on when you turn on the blinker, they light up the road like a head light off to the side, I can't even find one at the junk Yard that works, so I am going your way, but I need to figure out how to make the corning lights come on also, thank you very much for getting back with me

[@BadHombreGarage]

@@michelsmith5610 gotcha! I’m unfamiliar with those, and I’m scratching my head on how to wire them right now. You could tie them in with a blinker, but that would make them flash… so that’s not good. I’m guessing it’s a special switch integrated with the factory turn signal switch to power the cornering lights as the turn signal is selected. I cannot think of how to make one of these switches do that, but I’m hoping another viewer will chime in?

[@BadHombreGarage]

Thanks for watching, I'm glad the video helped. As far as the 2 prong switch, it's a simple switch so it doesn't matter which side the input from the power source goes to and which side the output to the brake lights goes to.

[@djv2305]

@@BadHombreGarage Also I forgot to ask, when switching from the 2 prong flasher, I know you said its in replacement of one of the 2 prong flasher, but do I need to remove both of the original ones on the harness or still leave them in when attaching the 3 prong. Sorry for all the questions but your video has been the most helpful I can find

[@BadHombreGarage]

@@djv2305if you go with the 3 prong flasher, you’ll remove both of the 2 prong flashers in the system.

[@colemtb1554]

Did you leave your 2 prong hazzard flasher installed in the fusebox, or use a jumper wire? On my harness, I would need that or a jumper wire for the hazzard wire to have power.

[@BadHombreGarage]

I removed the 2 prong flasher. I used Speedway's 12 circuit wiring harness, and the way it is set up I removed both 2 prong flashers in favor of just one 3 prong flasher. Then I used one of the wires (constant hot for the hazard 2 prong flasher) to power the 3 prong flasher.

[@valdutson1307]

Thanks for the help. I hooked the signal the way you show. Tried the switch but noticed the flasher was not putting out power after turning on. I did have a 20 amp fuse on the line. That probably blew the flasher. Can't figure why the blown Flasher. I changed the fuse to a 10amp but hate to try another flasher. I checked the flasher and it did have out put before turning on the signal. None after.

[@BadHombreGarage]

I guess it might have been a faulty flasher? Coincidentally, I have the same issue on my car right now... blinkers/flashers don't work. Once I troubleshoot I'll let you know if I learn anything.

[@benitorivera5360]

Hello, thanks for the video. I have a question, could you help me? Can the Universal Turn Signal Switch handle the full amperage of the front, rear and side turn signals (about 15 amp)? Or is it necessary to use 4-pin Bosch type relays? And in your case, what is the maximum amperage it supports?

[@BadHombreGarage]

That’s a great question that I, unfortunately do not have the answer to. I can say that I did not run relays and the switch seems to handle the loads just fine. Thanks for watching and commenting!

[@MarciaTyrrell]

Do you need to have front and rear blinkers for lughts to flash on switch itself?

[@michaelhughes2139]

Okay I've got everything hooked up on that switch unfortunately my hazard indicator light stays on flashing any advice would be helpful . I will know I do have LED turn signals

[@BadHombreGarage]

I’ve thought about this a couple of days, so here’s what I think. It could be the wrong flasher; they make a 3 prong flasher for LED lights. It could be that the turn signal switch itself is defective, causing your issues. Or, it could be a bad ground somewhere. I’d make sure everything was grounded well, including the steering column as this is where the switch gets its ground. If I recall, I think the LED specific flasher might even have it’s own ground. Those are my thoughts, hopefully someone else will chime in. Let us know what you find.

[@GameExplorersX]

If my wires aren't long enough, do I use hot wire to extend them? (For turn signals)

[@BadHombreGarage]

I’d just try to use some wire of the same color. Make sure you use a good connector or solder and cover the connection joints!

[@spiderchata1]

Does the 12 circuit kit have the single wire for one wire GM alternater? I came up on ur page just before i order a harness. Thanks

[@BadHombreGarage]

Yes! Per the Speedway instructions: "If you are using a one wire alternator the only wire you need is the ALT PWR=RED wire."

[@rocksaltmetalworks6350]

Do you know if this will work with an led flasher?🤔

[@BadHombreGarage]

I think it depends on the turn signal unit that you are using. I’ve heard of some issues with LED flashers, but I’ve also heard that some work. I know that isn’t helpful, but if you try it and it works please let us know.

[@rocksaltmetalworks6350]

@@BadHombreGarage I plan to for sure. I’m using the exact wiring setup you are and I’ll be sure to let you know my results. Per chance have you ever used manual brakes with the little single lead brake light switch with this setup or has it always been the two prongs switch?

I’m doing a 50 GMC panel with an American auto wire kit. I have power to the switch but it will not do anything. I’m trying to go through GM style harness to keep from cutting and splicing things. I do not have the rear singles wired yet and was wondering if if that is why nothing is flashing. Thanks for sharing

[@BadHombreGarage]

That could be the issue; I think the switch needs to see a load for it to work properly. I have used this with the GM style harness and remember it being pretty easy to wire in.

[@TheMiscreants-is9bu]

Hi Bad hombre. I installed this as directed, and everything works as it should however, in the neutral position on the lever, the flasher unit is still clicking, and the red light on the lever is blinking and no lights are flashing. I would expect the turn signals to not be on in the neutral position and that’s good but I don’t know why the flasher is still clicking.

[@BadHombreGarage]

Hmmm… there’s a chance the switch itself is messed up. I’d pull that flasher lever and make sure it’s seated well in the off position. Check your grounds- make sure everything is grounded as they should be- especially if you got one of those flashers designed for LEDs and it has a ground wire.

[@0deathmonkey086]

Im getting this exact same thing right now. Did you ever figure it out?

[@williambutler5541]

Hi I am also experiencing this. All the wires are hooked up correctly, and the positive is constant power. Indicator is clicking/blinking while in the neutral position and lights work as they should. Is this an indicator problem? like do i have to open the unit up? thanks

[@waynejodoin4063]

@williambutler5541...mine is doing the same thing. Did you ever get yours figured out? I took the switch apart and all looked good Here's the interesting part. I took a 12 v battery charger and hooked it it to the flasher, red to X and black clip to the clamp on the steering wheel. All worked as it should, directions and flashers. Back to car power, clicking but no turn or hazards flash

[@mjgrabowskillc]

Ok, I know these question are old, but incase someone has this issue in the future and comes across this video comment, here's what worked for me. First, make sure the flasher relay is wired correctly. Mine had the pilot (blue) and power (red) switched. Next, to stop the constant flashing in neutral, I just eliminated the blue (indicator pilot light) connection. That was the only was to make it work. I then went to Walmart and got a couple tiny 12v marker lights and installed them on my dash, wiring them into the signal wiring, and using those as the pilot light indicators. Anyway, hope this helps anyone in the future.

[@rustyriverband11]

What do the L wire and P wire actually activate ?

[@Cnedley]

Is the brake switch wire required? My turn signal is separate from my brake lights

[@BadHombreGarage]

I’m not sure how it will work without the brake light wire used. It may cause issue when braking and using your turn signal, unless they operate different bulbs.

[@VicForce-l6t]

Yes trying to figure out how to wire a led flasher on my 36 Chevy the led flasher does not have a L P or X

Sometimes the LED flashers do not work well with non-LED lights. Try to connect wires in the same pattern as the setup on the video, it might work.

if i am connecting red turn signal wire to brake switch what happens to the brake wire. do i splice in

[@BadHombreGarage]

One side of that brake light switch is hot, the other side of the brake light switch goes to the red wire on the turn signal switch.

[@gring_the_toe_snatcher1124]

Do I need a three prong flasher if Im not running hazards.

[@kramerflamer]

Keep in mind...the two prong flashers can be used if a separate 4 or 5 pin relay switch were to be used. You would simply wire the 2-prong flasher to pin 30 of the relay. This allows flashing for both the turn signal or hazard. If you're using the Conmutador Universeral Turn Signal Switch as shown in this video, it already has a relay switches built in for feeding the left and right turn signals and the hazards (not clearly explained in the mfg. instructions). That's why he's suggesting a 3-prong flasher. The built-in relay switches of the universal turn signal switch will feed power through the blue wire to the P terminal activating the flasher to work. This allows power to flow from terminal "K" and out through the terminal "L" out to your signals or hazards if it's being used. A 2-prong can be used, but it will take some experimentation on your and figuring out your own wiring diagram to make it happen.

[@BadHombreGarage]

Thank you for your answer! @@kramerflamer

[@richkennan5578]

Do none of the wires plug into plug connector coming out of the column

I am installing one of these in a 1922 chevy. All of my lighting is LED 6V and everything is working except the brake lights. My question is: Should the red wire to the brake switch be carrying current? Mine is not. If the red wire should not show a voltage and the brake switch is just a path to ground through the turn signal switch , should the power be somehow supplied by the left and right turn wires. I tried this. Did not work either. I'm, frustrated..

[@BadHombreGarage]

If your wiring is set up like mine, the red brake light wire is hot and goes from the power source to the brake light switch, then to the turn signal switch.
