Wiring backlights in front spots

[Grumpy]

Hi,
I'm looking for some guidance/ help. I am planning to install some spotlights on the front bumper, was looking to wire these through a relay into the mainbeam circuit, info gained from another thread.
The spots in question have backlighting which I was also wanting to utilise. I had hoped these would be on whilst either the DRL's, sidelights, headlights were on.
Question - can I take a trigger from each feed to a single relay to do this? Can something be introduced to each feed to stop current going back into the other two ?
They'll both be fed from ext 1 as the combined draw is 8amps.
Diagram attached to hopefully make it clearer.
As you can probably guess I am limited in my knowledge in electrics but always keen to learn something new.

Thanks

G.

You can purchase a loom with relays direct from Lazer lights UK, used then on a number of vehicles, will come with installation wiring diagram.

I have wire and connectors to do the main light setup off ext 1.
I was just hoping for a more suitably experienced electrically minded person that might be able to advise where my knowledge is lacking.
If taking the backlight supply from the other lights isn't viable I'll find another source linked through the ignition possibly.

Thanks

You are going to need two relays no matter what. I'm going to guess that you want the spots to come on when you turn on high beams and not just regular headlights and that the spots can have both the DRL's and the spots powered at the same time. Let me know if either of these assumptions are wrong and I'll remap the wiring.

First build a short wiring harness that goes between the 6 pin headlight feed and the headlight so you don't have to cut into those wires. It's a standard DT connector. I posted about this before when I did something similar. https://www.theineosforum.com/threads/high-beam-connection-for-lightbar.12413323/post-1333317433

I would wire the DRL's to relay 1 as follows:
Terminal 85 to ground
Terminal 86 to the DRL feed of the headlight. This way the spot's DRL's come on with the headlight DRL.
Terminal 87 to the spot's DRL wire
Terminal 30 to the battery post connector under the hood.

The spots on relay 2 I would wire to the high beams. Here is where you have a two options depending on if you want them to always come on with the high beams or not.
Option 1 - The spot's high beams will come on whenever you activate high beams from the stalk.
Terminal 85 to ground
Terminal 86 to the high beam feed of the headlight.
Terminal 87 to the spot's high beam wire
Terminal 30 to the battery post connector under the hood.

Option 2 - The spot's high beams will come on whenever you activate high beams from the stalk AND have the Ext1 switch activated. This allows you to not always have the spots come on.
Terminal 85 to ground
Terminal 86 to the high beam feed of the headlight.
Terminal 87 to the spot's high beam wire
Terminal 30 to the Ext1 connector under the hood. Double check that you are not drawing more than 10 amp.

The nitty gritty​

The STEDI™ SMART Harness suited for the Ineos Grenadier is for those who are looking to run auxiliary lighting using the factory switch controlling the grille lights. This all-in-one solution is perfectly designed to be unobtrusive with specific crafted lengths to ensure adequate cable management.

Our aim was to create a stress-free installation process allowing for use in conjunction with the factory grille lights or as a standalone just for auxiliary lights. Giving you peace of mind of knowing it will come together in the end.

• Featuring a total of 4.8 meters of wiring (fully extended)
• 2.4m of cabling from Relay to Switch
• 2.0m of cabling from the Driving Light connector to the Relay
• 2.0m from H4 or HB3 Adapter to Relay
• Total cable length 6.4m
• 12vDC 35A Rated Fuse Kit
• 12vDC 60A Switching Relay
• Push Button ON/OFF Switch
• UV Rated Insulation
• Instruction included.

Commodore,

In fairness It was after reading your thread previously that set me down this road, so your experience will be greatly appreciated.

Looking at the light patterns, when I scroll through the headlight operation, there appeared to be 3 different lighting patterns: DRL's - outer halo lit brightly
Sidelight - outer halo lit slightly dimmer
Headlight - inner unit lit but no outer halo

I assume that during the sidelight and headlight phase that the DRL's would not get power, so there would be no backlight DRL?
I was trying to avoid this and thought the introduction of something, inline diode? May allow all three triggers to be connected together onto 86? This may stop power travelling back to the other cicuits?
This is where my knowledge is maxxed out.

So thanks for the initial response and any diagrams would be greatly appreciated.
And any further thoughts suggestions will be greatly appreciated.

You where correct with option 2 for the spots.

Thanks

G.

What about a single 5 pin relay.

85 to ground
86 from high beam feed
87A to spot's DRL
87 to spot's high beam
30 to battery post connector under hood.

High beams off - spot's DRL on, spot's high beam off
High beam on - spot's DRL off, spot's high beam on

High beam on - spot's DRL off, spot's high beam on

The DLR's would be on all the time... even when the car isn't running. pin 30 provides constant power to 87a unless 86 is supplied power. When 86 is supplied power then it moves the output from 87a to 87.

Let's start with what you want to accomplish. When do you want the Sidelight and Halo lit up? BTW: what lights are you using?

Crap, that’s right. Nix that idea.

Commodore,

Okay i'll try and explain more clearly;

Additional Spotlights operation
Operation of the spotlights themselves is sorted, feed from EXT 1 via a relay that's triggered by the main beam wire coming from the headlight 6 wire loom.

Additional Spotlight backlight operation
Would like these on a whilst vehicle is operating when;
1. DRL's are on,
2. Sidelights are on
3. Headlights are on

So looking for a way that power can continue to the backlights whether any of the above states are present.

So a trigger would be required from each of the feeds in the 6 wire loom for , DRL's, Sidelights and Headlights.

So my hope was that the 3 potential triggers could combine to a single relay terminal 86, and operate the backlight. But to do this there would need to be away to stop a back feed down the 2 other triggers that in are not in use at that point. So my optimistic hope was there was a way of introducing a non return for the power on all the triggers that only allows current to pass one way to terminal 86.

Appreciate your interest and assistance. Hope this helps.

It’s going to be a 2 relay system but you can get away with only using Ext1. Aren’t the DRL’s always on? I think they stay on even when the headlight are on. Use that to trigger both the spot’s DRL’s and sidelights or if you want the sidelights only on with the spots then use the high beam signal to trip it along with the spot. Basically, use a trigger wire to turn on 2 of the 3 spot light functions.

Again, check to be sure that you can actually feed power to all 3 functions at the same time. My aux lights have a high and low beam and you can’t feed power to both at the same time. The high beam internally powers the low beam. So I had to turn power off to the low beam when I power the high beam or it cooks the lights. I didn’t bother wiring the DRL function because I keep them covered on the road so the police don’t ticket me.

I think our lights are wired slightly differently to yours.
Our DRLs are quite a bright outer halo.

When sidelights are selected the halo dims a little

When headlights are selected the the halo returns to bright but also has the upper section of the lamp lit

When main beam is selected the halo keeps bright along with the upper and lower sections of the light

When i create the short harness i'll check what each wire is doing and and see if theres any logic, assuming that there are only two option, outer halo bright and outer halo dim i could use a 5pin relay?

When i get around to it i'll update on hopefully what wire controls what function in the light cluster.

Thanks for you help.

I'm due a visit to the SS shortly so if i develop a fault code they can rectify!

The issue with a single 5 pin relay is that the function on 87a will be constantly on even when the car is turned off. 87a and 30 are normally closed. When you apply power to 86 then it switches power form 30 to 87. Does that make sense?

Yes, so if I pull the feed for both the backlight and spots from Ext 1via a relay for each circuit, 5 pin for backlights and a 4 pin for spots and the total draw is below 10amp it should work.
Spots triggered from main beam.
Backlights triggered initially by DRLs but swapping to side/ headlight if used.

Does that seem viable?
