Wiring and connecting Extra lighting Siberia 9"

[LofotenDisco]

So Ive fitted 3 of the Siberia 9" Lights on my Disco 4, 2016 model. Ive used this kit from Siberia, and i cant seem to understand if i need to use the blue wire in order for the Lights to work, or if i did something Else wrong.

The RED wire is connected to the battery, the BLACK wire is connected to the ground/chassy. The BROWN wire is connected to the Black/Blue wire that goes in to the right hedlamp. The BLUE wire is not connected.

I followed a guide from a post here to find out What cable to Connect to, but Im no electrician - so it might be wrong.

Any help would be great!

Is the aux light relay pre wired?

Terminals on the relay should be wires like this
Terminal # 3; Fused, 12V in.
Terminal # 5; out to aux lights.
Terminal # 2; 12v from headlight, with an on/off switch inline.
Terminal # 1; direct to ground.

I'm not either, but according to the site and directions you linked to, they say this about blue wire 87a "Blue cable (87a) second output can be used with a multifuctional relay. " so it reads as though it doesn't need connection.
