It's page 64 and on.
Nicking 3W looks 'possible' to me. Total of bulbs is about 12W, so depending on how the dimmer actually works you might lose maximum brightness. I'd give it a shot.
Ideally I'd connect to the +ve on the dimmer switch, but taking it from +ve on the lighter bulb wires (not the main one for the lighter) should be OK.
Anyone agree?

Ref page 236 sunroof and illumination
As a side note need a switched live for my aux fuse box, haven’t got a sun roof so thinking of taking a 12vdc supply from the sunroof , fuse number 20 and rated at 15 x amps
So aux fuse box doesn’t get any power when ign is off
Noticed there is also an illumination within this circuit , just mentioned it in case it’s of use to u

Ah, crossed posts, but not wires! Yes the lighter would be OK, prefer the dimmer switch because it avoids extra load in the existing wires,
Many thks, the lighting connector that useto be on the lighter is now redundant with some heat shrink over it
So will re utilise that then
Bless u as always for the fantastic help
My fault , lol
Many thks as that connector isn’t being used , is it best to join all 4 x positive wires to that connector so it’s in parallel plse
Will pick an earth up from the dashboard

Yup, parallel. If you're using twin flex you could earth at the dimmer switch while it's under your nose..
Many thks , pic of where my the dimmer switch is located , is also inside a box, just has a connector out the back of it
Can see in this pic where it is
Have got some spare rolls of 17.5 amp cable I was going to use up
Daft question if i may please , do u think that would be ok to use please
From the cig lighter connector ( lighting one ) was going to fuse the cable that goes to the wheat bulbs, using a 1 x amp
Wondered as the main circuit is rated at a max of 10 x amps if the 1 x amp fuse would pop , or need to rate it the same as the rest of the instrument panel lighting amperage
Many thks

17.A cable is overkill, but if it's free, go ahead, less heat, more power! I wouldn't bother fusing them - just either disconnect the battery or at least take out that fuse 25E while you're waving the wires about.
Thks, indeed have the spare rolls so handy it’s ok to use , batteries are both currently disconnected
ref the fuse not req, is that because the circuit is already fused then plse ,
Bless u and very grateful

If you short to earth cable capable of 2amps max then it will burn before the 10amp fuse blows. Think for a few minutes about the number of car fires where it starts behind the dash. If the power available to the wire powering the LEDs is higher than the rating of the cable, and not limited in some way, then high currents are available if you catch the wire on an earth. If yer powering the lamps from the eggsisting dimmer then it should be ok to limit the current, so no fuse needed. Be careful on cable current carrying capacity. Temperature makes a difference. The absolute max is when yer happy for the cable to get quite hot.
Hi
Not going to use a 2 amp wire as indeed I always use cable that has a higher rating than the fuse , Am using up some cable which is rated at 17.5 amps,
