Replacing Park Assist

Have worked out that there is a problem with either the park assist module or the sensors, so I have decided to remove the original Jag kit and replace it wit an aftermarket kit and do the front as well (which hasn't got any). I know it won't be as smart looking however it will be a lot cheaper.

My question is, Where is the best place to get the wires for the front sensors through the bulkhead into the main compartment of the car? here dose the wire loom come through?
