You don't use one relay for each bulb, you use the relay to power the lows, and one for the highs.
You use the power connector that normally lights one of the head lights to power or pick the relays.
Now here is the diagram that I used to make mine.
Here is the 3 relay one that allows both low and high beam on the 7inch to shine when you go
HIGH, as well as the center high.

For low beams
Pin 30 - positive from battery with 20amp inline fuse
Pin 85 - earth ( could I connect this to the battery negitive or does it have to be from the light harness)
Pin 86 - the input for the low bean
Pin 87 - the out put to the lamps low beam ( so this will have 2 wires coming from it one going to drivers lamp the other to passenger
For high beams
Pin 30 - positive from battery with 20amp inline fuse
Pin 85 - earth ( could I connect this to the battery negitive or does it have to be from the light harness)
Pin 86 - the input for the high beam
Pin 87 - the out put to the lamps high beam ( so this will have 2 wires coming from it one going to drivers lamp the other to passenger)
I won't be running my inner spot lights
Hope I got this correct please do correct me if I haven't lol

use the uk site, you can't make it cheaper. I just did this to my van that used 9004 bulbs, and had to find replacement sockets….. But it don't get much simplier than this kind of kit.

Basically, you can also buy a standard headlight relay loom from epay that is plug and play.

I bought some of the link type looms direct from China and have used 2 of them know on the cabby.
Problem I've found with them is that when you put the side lights on the headlights come on and there is no way to light only the side lights.
For Mynx I ended up making my own loom as I wanted it inside the car and followed one of your useful guides and ended up with everything working the way it should.
I wonder if it's something to do with the earths being separate from original lighting loom or something.
Just wondered if with your vast knowledge you might have an idea?

My big issue was the wire color changes on the 9004 sockets.
My marker lights work fine.
On my design of the loom I just figured it was easier to run one extra wire and control everything from the left or right original headlight plug….
The relay are grounded to the same point as the headlights so there wasn't a small differential.
Of course there is the 2 or 3 relay version.
The 3 relay version allows the high/lows on the 7 inch bulbs to both be on and there is a heck of a lot more light.
I think they just made the "chinese" ones that way for cost reduction… as there is less wire to run.
my two versions are:
I have been tinkering with the idea of doing the alternating side marker to front flasher blink…

when I built them back in the day I had used 3 relays and fuses as I used to buy a handy relay holder with 3 fuses built in and 2 single relay holders which would clip to the side of it. 2x 10a fuses for the dip and a single 20a for both mains

A 10a rated wire with 20a fuse on it would not work as intended
but yeah no need to go larger than OEM on the fuses, 10a will do you fine if you're running 1 per side for dip and for main. I went for 20a on the main because I had both sides thru the a single fuse & 30a relay

I installed one of those kits from ebay. Simple enough. Worked fine …but now not so much. I have one light at I'd say 50% of power and the other barely on, maybe 20% of power.
Haven't changed anything but could it be a bad earth?
Dodgy dash switch?
Any ideas welcome…

Bad grounds or connections can be a problem on either Positive Sides or Ground sides of circuits. But then again on my Original Golfs (Westy Rabbits) my Passenger light bulb always burned out first about every 12 months.
If your Voltage is 12+ to frame, then check it to the Bulb ground… If the voltage is different, then you got your answer.
Yes I know that the Normal Voltage on my ride was +13.75 DC. (Car Running), Good grounds only insures that you can have maximum current flow in the circuit.
If you haven't checked for Voltage drop on your major grounds, Do so as it only helps eliminates weird things.
My Quick test for Main ground issues is easy.
Take a set of Battery Jumper Cables.
Attach One of the Black leads to the Battery Ground post, the other end to a Strut mounting bolt.
Attach the one of the Red leads from the Battery negative Post to the Engine Lifting EYE.
If every thing Brightens up, bad grounds. If you go from 11.5V to 13, bad grounds.

And the one running at 20% - the bulb gets very hot, very quick.
Have checked voltage to both and with no ignition, 11.6v

Maybe the bulb holders are corroded and need a buff up

So came back to delete my OP - but you’d already got there!!!
New bulb holders next on the list…

Use a DVOM, to Measure the voltage at your light sockets.

Me again.
So to check grounds on my very dim sidelight, i ran an earth staight from the bulb holder to the battery. No improvement . The bulb was still dim and heating up quickly. Also fiited a brand new holder. Same.
I also tried the Quick test for Main Ground issues. But i'm not sure i got it right.
Isnt the "Battery ground post" and the "Battery negative post" the same thing? Have i lost something in translation?
