I have made a little more progress on fitting footwell lights.
After disassembling my interior light I found that the front and rear bulbs are directly connected to VNQ810 IC chips. These "QUAD CHANNEL HIGH SIDE DRIVER" chips have 4 outputs each. Unfortunately there are only two 12V outputs and the rest are all 0.62V
Maximum output current of these chips is 3.5A per channel, so it isn't a simple case of running wires to extra bulbs in the footwell.
I am now working on building a simple circuit to switch a transistor/relay combo to illuminate the footwells.
