    Does any one have experience removing the main hybrid cable connecting the hybrid battery and the inverter under the hood? I know the cable runs under the car and up to the engine compartment. Is it hard to remove?

    I see that there are some bolts and clips to unhook but are they all reachable without taking out the brake actuator or inverter?

    Unfortunately, I installed a new hybrid battery and didnt torque the nuts down enough and it became loose. The arcing burned through the wires at the relays next to the ECU near the hybrid battery. I was thinking of splicing the wires back onto the connectors but I thought its safer to just replace the entore wiring harness. Any help is appreciated.

    They're really easy to take out probably why no videos. 9 hoot two here ready got this removal 8 thought not needed no one would ever need . In plug orange plugs at back of inverter of course safety plug removed from battery. roll car on ramps. You see the two plugs you've undone from inverter they run in a plastic tray that bolted and screwed to under chassis as you drove the screws n bolts out of tray it'll start hanging down .. you make it back to tear of car and pull thru the eyelets that bolt to HV battery . And the whole mess is on you're grass or driveway . Reverse the process . Not hard you just have to participate . Be able to lay under car . Move arms etc .
