Thread: Piggy-back/ splice Cig Lighter Circuit - Advice sought...

If so, that is right next to the seats and should be easier to pick up.
Alternatively, is there already something in the battery box that is only active when the ignition is switched on?

That's what I thought too, Mick, so I called Daniel yesterday to ask him. Once he'd finished laughing at the idea of Monty getting heated seats, he said he didn't think there was anything in there which is switched power - he even went to his 2008 110 to check....then he suggested using the Cig Lighter circuit behind the dash as it's 20A. I would love to find an ExBox solution as I need to feed wires through it anyway - the seat switches are going on the cubby box....so if I can avoid wiring going forwards to the dash just to pick up 12v power, that'd be awesome.

I don't know of anything in the battery box which would be switched power.

Seats installed, piggy-backing the cig lighter positive wire worked a charm. All working as planned. In-line fuses on the +ve wires for each seat are 7.5A. I used an existing earth inside the Ex Box.

VERY comfy seats!

Rob, i ran a trigger wire off the ignition to a 50amp relay in the X box that supplies +ve to half of a 12 blade fuse box (the 2 x +ve terminal Narva type). Half the fuse box has a constant +ve source for things that are ignition independent and half the fuse box is triggered by the ignition (only gets +ve to the fuse box when the ignition is on). since you have already run a wire from the cig socket that would be ignition switched, you could do what i've done with a spare morning (or afternoon during or before beers).

I have almost the same setup but only 4 circuits and all constant, no switched power, so at some point I might get a larger one and replace it and do the ignition thing but the set-up I've got will do for now.
