Interior light wiring route

Featured Replies

I'm thinking of adding extra LED lighting strips under the dashboard to light up the foorwells and then also under bottom edge of the front seats to light up the rear footwells. Does anyone know how the interior light wiring runs and how easy is it to get to so as to run the feeds off it to the new LED strips?

I'm just wanting to know as If it's a bit of a ballache job i might just pay a few quid out to a autoelectrical place and let them have the hassle.

Cheers

LED strip lights take very little current, so you could use the instrument illumination circuit, which would also give you the ability to vary the brightness. Suitable feed is on the lighting switch from the variable brightness potentiometer.

Good idea but i'm wanting them to come on/off with the interior light when the doors are open and not be on all the time when the lights are on.

Ah right, in that case you want the Red wire with Black Tracer. Easiest place to pick up this wire is from the glovebox light.

So is the glovebox light lumped in with the interior light then???? Does that mean whenever the doors are open the glovebox light comes on too? Though then again if i fed the new LED's off the glovebox wiring wouldn't that mean they only come on when the glovebox was open rather than when one of the four doors is open?

You are correct, my mind wasn't in gear when I wrote that drivel :rofl:

What you need to do, is wire the LEDS across one of the interior light bulbs. That way they only come on when the ground lead is earthed by a door switch. You could pickup the wiring at the voltage control unit under dash drivers side, or from a door puddle light.

LEDS are polarity sensitive, so you need the LED negative wire connected to the switched side of the bulb you wire across.

From the interior light I am 90% sure it goes to the left and down the nearside A pillar to meet up with the rest of the wiring - probably goes around the fan for the venting, and to the right along, behind the dash to the main area of "circuitry" I can recall the roof aerial wire goes along the top of the car on the nearside.

Ok. I am trying to do the same mode here and put strip lights in foot wells etc when a door is opened. Unfortunately the only interior light bulb I can wire across is the main overhead one. I was hoping that I could wire into something behind the glovebox or drivers side.

Is there a wire that runs down from the main light that I can use?

I have a mk1 octy RS if this helps. I just realised I'm in the wronge place for this. Sorry

Any ideas?
