Fender side markers - need wiring advice

This is great! I will try this as well! My question is, will the marker lights be on whenever the vehicle is on or only on with corner lights? Would preferrably like them off when corner lights are off. So essentially the markers would be on only when headlights are on.

 

I am using factory turn signals and corner bulbs. The bulb in the side marker is a 194 I believe - the smaller type lamp. Not too sure what the amp draw is on a 194. Would you happen to know?

 

Less than half an amp if they are incandescent. Less than a tenth of an amp if they are LED. Should be fine. And you should be able to piggyback off the stock wiring fine.

 

They are on per what ever you want the input to be and there begs the question. I indicated ignition on but you could have it be the corner lights.

Question is. Would you have the corners off and still want the markers to blink with the turn signals?

If so....I think you need a 5th relay. The 5th relay would replace the ignition on in the diagram for when the markers are on with the corners. This 5th relay would give power from the battery to right and left relays when the corners are on.

I can re-draw this later.

like these? 3.78 watts

 

Again dotted lines cross other wires but don't connect. In this one your corner lights power the side markers so that fuse better have enough amps. This has 4 relays total. 2 for the right and 2 for the left to co trol both sides independently and for example would keep the left side marker on constant while you have your right blinker on and the right side marker blinking in time with your blinker.

So the corners power the side markers until the blinker goes on. I've been reading that the blinker relay is in the ECU? That sounds insane but if accurate you would need to pull the trigger from your steering column I think. That cuts power to the side markers when you out the blinker on but only to the side of that blinker; right or left.

The lower two relays make the side markers blink in time by using the power source of the blinkers as the trigger. These relays are powered from either the battery or an ignition on source. If by battery, the relays wont pull power until triggered by the blinkers.

 

It is on one of the modules. Might be BCM. But yeah, kinda sucky

 

So I can’t post a video and not making a YT account just to post a link. Just went out and found the modules in my garage. Both positive outputs to the same light. When power is applied to the turn signal input, it immediately cuts power from running light and applies power from the turn signal input. When there is no longer input from the turn signal, there is a 1-2 second delay before the power from the running light is turned back on. This allows the light to not be constant on while turn signal is going. Very simple and easy solution to what @Emmantik is looking for

 

This is great! Thanks for sharing!

 

Just received the switchback module and installed it. Very simple solution to what I was trying to accomplish.

 

Does it work exactly as you wanted?

Edit: that was a dumb question on my part. You would probably have more questions if they didn’t work how you wanted

 

This is how exactly how they are wired. Only difference is I tied together the running & turn wires together (on the output side) that goes into the side marker.

 

Yup works exactly how I want!

 

Yep! That’s the way I used to run them. I actually realized I have 4 of them sitting in my electronics drawer in the garage so now debating how to use them…
