I want blinking marker lights.

While sitting at a 4 way stop sign during the day, I happen to think that the person to my left most likely wasn't able to see my front turn signal due to it being set back in the body work.

Anyone hooked up right side markers to right side turn signals and left side of course like many "modern" cars are ? Thought I'd ask before I start cutting and splicing.

I have not seen it done but would be easy enough by adding a relay.  Would you do front and rear markers?

Thx for link, interesting.
Wish he would provide a pic and the wiring diagram, not just instructions.
Makes it kinda hard to visualize how this would mount up.
If small and you could catch all the connections under dash, I'd consider it.
If it needs to be in engine compartment and running wires everywhere, forget it.

I used the crossfeed method on my daughter's '68 Dart, mounting relays at both fenders (nothing in the dash). It worked fine. If I do this mod on my cuda I would probably use the module.

Scroll down the post. There's a diagram.

I would just do the front.

I was referring to his box, not the "DYI" options.
I realize he spells out the connections.

Have wanted to add this feature to mine also. Could be accomplished simply with relays.

I'm sure @crackedback could come up with a plug and play relay kit for this.

[70_440-6Cuda]

With a relay and the proper gauge wire this could be done easily from either under the dash or under the hood.  Depends on if you are only activating front markers, or both front and rear.  You could place 2 relays under the dash and pick up ground and the TS input under the dash, run the 2 wires from Pin 30 and 86 out to the marker light.  You then just need to "interrupt" the positive feed to the marker light with the 2 wires from 30 & 86.

This set up would be alternating flashing of the parking light and the marker light.  If you wanted synchronized flashing it is the same principle with slight variation in wiring the relay.

Pin 87a connected to the parking light feed
Pin 30 to the marker bulb
Pin 85 grounded
Pin 86 to the turn signal input
Pin 87 left unused

I'm thinking you might also need to change the flasher to an electronic one. The originals flash at a rate determined by current flow...if you add more lighting to the string there will be more current so a quicker signal flash. How much two marker lights will change the rate? I dunno.
If you already have LED signal lights...so already have an electronic flasher installed...nothing should change.

That actually would not apply here - you are not adding any load, you are using the relay to simply "disconnect" the marker light for the duration of the turn signal light when on.  In the relay diagram I posted, the dashed line represents the marker light wire - you can cut it, or disconnect the "hot" wire at the marker light plug to put the relay "in line".  Terminal 87a and 30 are Normally Closed (N.C.) so the marker light is basically connected as if stock.  Once the turn signal is on, the positive feed from the flasher to the light (attached to the relay at 85) activates the relay disconnecting terminal 87a and 30 - you are essentially unplugging the marker light while the turn signal is on so they will flash in an alternate pattern - turn signal on, marker off / turn signal off marker on (meaning the marker would be on when parking lights are on).  The relay only uses about 150mA so should not create any issues with the flasher.

Hope that helps

You are adding load to the cct with the relay coil...no?
