Fender side markers - need wiring advice

[emmantik]

Looking or expert advice on how to wire side markers how I would like them to operate. I currently have them wired up already to turn on with turn signals and corner lights but not operating how I like.

How they are currently wired with a 5 pin relay (pic below) as per this video I found on the subject;

The only thing I don’t like about how this is wired is;

1. Turn signal on the fender marker ONLY works when the corner lights are on. When corner lights are off, fender markers won’t flash with other turn signals.
2. Turn signals are not in sync with all the other turn signals. They flash opposite of normal turn signals, alternating.

My goal with fender marker lights;

1. Turn on with turn signals and operate all the time regardless if corner lights are on or off.
2. Turn signals flash in sync with other turn signals.
3. Turn on with corner lights.
4. Turn on with corner lights and when turn signals are used - flash in sync with all other turn signals. When turn signals off – continue operating with corner lights

Any advise would be appreciated on how to accomplish this.

Thanks!

You will need to use a 6-pin relay.

These are the steps:

Connect pin 85 to ground.
Connect pin 86 to the turn signal wire.
Connect pin 87 to the side marker light wire.
Connect pin 30 to constant power.
Connect pin 87a to the corner light wire.
Connect pin 85a to ground.

I hope it will work. Come back with a feedback.

Thanks for the info! I will give it a try and report back!

Decided to go with a switchback module from Diode Dynamics. Should do exactly what I'm trying to accomplish. Seems to be the simplest way to go.

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