Best place to tap DRL wire for accessories?

So, I have the Baja S8 20" light bar to hook up soon. It has a backlight feature that is most commonly hooked up to the DRL circuit, from what I can tell. This backlight feature is secondary. Primary feature is, of course, the actual main lights of the light bar. I have the primary light circuit sorted, as I have an aux relay/fuse block that I put together last season. I left a relay free for this eventual install, switch is already wired up inside in the dash, etc.

My questions is, what is the best way to tap the DRL circuit for this lightbar's secondary feature? Tapping one side's headlight wire seems too hackish to me. Is there a better tap in the engine bay on the stock fuse block perhaps? I've seen some posts with this info long ago, but am searching TW now and not seeing what I am looking for out the gate.

@caribe makaira is usually on point for these sorts of questions! Sorry if you've already answered this in 10 places and I am just too dumb to find it yet!

I'll keep searching... thanks in advance!

 

@daveeasa can hook you up to the required gadget. It would be a T between the DRL connector from the vehicle harness to the headlamp.

 

Any concerns with just tapping one side of the harness, as in, to one headlight vs the other vs at the source of both so it doesn't imbalance the circuit? One headlight load would include the accessory, the other headlight would not. Maybe I just don't understand how electricity works?

 

Most likely not. Just don't go adding a half dozen light bars with the same feature to it. That would require a very different solution.

 

Just this one light bar's DRL feature is all I am planning to add to this circuit. Still, I'd rather hook it up to the source of both headlights DRL circuit rather than to one headlight's side or the other...

 

If you find a way to slip a tap on the DRL relay leg that sends power to the DRL lights I would "clear" your doubts. But it's very difficult since the relay location has barriers on the sides.

 

Plus, after low beams are selected the DRL circuit shuts of, hence the T harness @daveeasa can provide ya.

 

DM sent to @daveeasa - thanks!

 

P.S. Harness does NOT work for Tacoma's with incandescent lamps for DRL's.

 

I'm in progress with @no vtec 4me for the BHLM w/ Amber DRL boards/halos. Upgrade to MLED headlights.

 

In for the solution as well. I have the Rough Country LED light bar with integrated DRLs. Is a harness needed?

 

Only if you want tied into the vehicles DRL circuit...

 

QQ: If I buy one of these

$39 Roadmaster 792 Hy-Power Diode, (Pack of 2)

thingies and wire a tap from the DRL wire and a tap from the Parking wire into one end and then a wire to my Diode Backlight out the other end, will it work to keep the Backlights on for DRL and Parking only?

 

Yes

 

Awesome! Thanks! Do I need one for each backlight or do you think I can spice the backlight wires and just use one diode from the drivers side headlight?

 

One is enough, but 2 are convenient for the install.

 

Very cool.

Picked up one of

Hopkins 56306 Quick Lock Diode, 1 Pack

these because it's a little more streamlined. I will hook it up and report back. Thanks again!

 

It be nicer if those were "pass-through", not end of wire.

 

I can only find those and the Roadmaster ones, which also seem similar. Tried searching for inline and pass-through with no luck. Any suggestions?
