Quick query.

For IVA can you run electrics on the same side of the tunnel as fuel pipe with fuel along the top rail and electrics along the bottom? Or do I have to have it on the opposite side?

Thanks in advance.

It's not a problem as long as they are fixed with separate p clips

so can you cable tie the spiral conduit in the engine bay but must p clip along tunnel and rear end?

Top and bottom will be fine as will opposite sides. Both together will be frowned upon (but might not fail if they dont touch).You can P-clip or zip tie but dont use stick on tie bases unless you put a pop rivet through them.

I used THIS sort of zip tie fixed through holes in an ally strip in the tunnel (fewer holes in the chassis).

i have zip tied mine to the outside of the top chassis rail on the tunnel. suppose id better sort that out then. i have p clipped the fuel lines and brake lines to the ally floor along the bottom of the tunnel.
