Is there routing for the diesel heater pump wiring through this mounting plate? Lots of "Generic" units have a slot by the air intake for this cable to drop through along with the pipe work? Or does the plug for the pump need to be routed separately?

It is always recommended by Eberspacher to route the fuel pump wiring through an alternative location, rather than through the mount plate. Quite high temperatures can be found close to the heater exhaust outlet pipe at this location. We always route alternatively at Butler Technik. Thank you
