ok so what and were is the best spot to run wires through the fire wall on a safari...
in this case its for a boost and etg usualy I run them round the door but thats a tad untidy, and theres already a bunch doing that.

drill a rust hole out with a step drill and use a rubber grommet to protect wires . Solves warrant issues as well

The above is good advice, except they tend to rust on seams, not so easy to drill!
There is a drain/bung/breather behind carpet on passenger side footwell (also exhaust manifold side) which you can poke wires through if you're precious about drilling. I can't remember if you have to remove the heater core to reach it on the inside or not.

I have used the big rubber grommet on the passenger side (by exhaust manifold)
I just poked a hole in it with a hot screw driver below the cables that are already in there.

sorted... followed a heater pipe through the wall, spotted it as the rubber had perished and I seen day light LOL... its near the stearing rack
