best route wiring ?
 

Hello guys, I am installing a siren on my X, got the siren under the secondary air pump, that's where I had more room, now, what would be the best route, to get cables all the way through the firewall and under the drivers dash??

Thanks!

through any pre existing rubber grommet thats already installed in the firewall.

Probably the location in this DIY. The grommet at the driver side in the pics.

If you need to run it across the engine bay from the passsenger side - go through under the wiper arm cover.

See pics in this DIY below.
