T5.1 Parasitic Drain Fuse SB12

It is.

I dont actually use the van sat nav as its well out of date. I use google maps on android auto and bluetooth to the car audio. So I guess i could disconnect this? Assume it will plug into the head unit

According to @sidepod wiring diagram there are 2 fused supplies to the switch SB12 and SB22.
What happens if you remove SB22 but not SB12?

I'll try again later. Its a small 7.5 amp in the middle row. I did check all the fuses but its worth double checking thanks.

Yes. Should plug into the back.

I assumed if Charlie removed the switch he would've removed connector T10 which also includes the SB22 feed?

Just to clarify I removed the switch by pushing it in on off then turning to dipped and pulling the switch unit out. I then uncoupled the electical connector and retested the draw

Couple of updates. I retested the draw on the battery with fuse 12 removed and it was Zero. Put the fuse back in and its back to 130mAmps. One thing on the light switch. When I removed it I just take it from the housing and disconnect the switch from the wiring block. So wouldnt this still be connected to the battery as the fuse wire is part of it? Im assuming its the red and black lead on number 8 connection. So my next question if this is correct....how do I disconnect the wire? Do I need a special tool?

This is what I was describing earlier. Remove the fuse and it will isolate that Red/Bk wire. Run a single wire (of similar size) from the battery and (somehow) poke it in terminal 8 (you'll need to de-pin it ). Reconnect the connector to the switch and re-test. This will prove the section of wire between fuse and light switch. You could do a volt drop check on it too (circuit loaded).
You can de-pin a terminal with a fine pick or small screwdriver. There is just a tang that needs pulling back to let the crimp slide out. Some are easier than others. That's quite a big one so it should be easy. Google a few images of various connector crimps and you'll see what you're looking for.

Just to be clear - with the switch disconnected from the terminal block, is there a draw?
