Defender wiring problems with cigar lighter

Hi,

I am struggling to find the problem that I’m having.
So I have a 110 with a 90 pickup body with no rear wiper and I removed to cigar lighter because I don’t smoke but now the wires have no power the only one with power is one of the green wires is there a relay that is broken?

I am wanting to use the lighter wire for switches and same with the wiper wires

Thanks

Fuse might be blown, the factory set up has fused power supply, ground and illumination live.

The wiring colours you’ll have to consult the wiring schematic for that, you can also use a multimeter to check for voltage, obviously the illumination is only supposed to be on when sidelight or dipped is, the power when ignition is on.

The fuse for the supply has possibly* been blown, there isn’t a Relay involved, the fuse is under the steering wheel in the factor fuse box. TheThunder Rolls🇬🇧🇺🇸

I’ve checked the fuses and used a multimeter but not when the light where on I’ll check that
Do you mean in the middle under the radio fuse or is there hidden ones behind the gauges I do t know about

Thanks

This link might help you.

Red and light green is screen wiper motor to switch
Red and yellow is the fog lamp
Black is earth
Brown is permanent live
Cant tell if the darker greens have a tracer but plain green is accessories fused via ignition switch.

Hope this helps

That link is useful thanks 👍

My brown has no power. Just need to check the side light wiring still and the only 12v ignition is the green wire
