Whats the best way to run boost gauge and oil temp/pressure wires from the engine bay on a sapphire?

I'd prefer not to drill any holes if possible!

Thanks!

 

There is a big loom grommet on the passenger side of the engine bay quite low down. There should be a spare insert or 2 in there you can use. Comes out right by the ECUs behind the glovebox.

 

As above, or if going in a pillar pod, You can run them along the top of the bulkhead with the washer jet pipes, then through a gromet on the drivers side and take the speedo clocks out and they can just go straight upto the pillar pod

 

Thats great guys, cheers!
