HV Wiring Conduit Installation

There will be three HV cables running between the rear and front of the car - the HV+, HV- and HV/2 cables. In order for these cables NOT to run through the passenger compartment, I decided to create an under-car 1.5" PVC conduit in the center channel where the exhaust pipe used to be. I started as near to the rear box as possible. Here is a picture of the rear inlet.
Cables will enter it from a center space under the reinforcing member. From there, they travel through the space formerly occupied by the fuel tank, over the rear axle and into the center channel...
Three brackets constructed of 1/16" steel are bolted in through bolts placed in the floor of the car.It resides well-protected in the center channel. Getting up into the engine compartment was a bit tricky, as I had to navigate around the steering rack.From here it's an easy route up through the passenger side corner of the engine compartment. I did a test run of one 2/0 cable, and although I purposely avoided many right angles in the route, the cable still wouldn't go on its own. Time for some fish tape to help with the cable pulling.
