Thanks looks like I’ll have to take it out and redo it. Hope i didn’t sever that wire.I asked Theo for install instructions, which need to be updated. I asked him for clarification about the roll-over sensor/wire. So below is the clarification I got from Theo. BTW, don't mess with the sensor, you just need to disconnect and reconnect the wire.
"The cable that connects to the roll-over sensor must be disconnected from the sensor (sensor is mounted to the load area chassis) so that the drawer can be placed on top of it and then the sensor can be reconnected. This is so that the drawer does not crush the sensor’s wire. The wire must be fed over the drawer’s rear cross member / floor beam / “top hat” (as it is called in South Africa) so that your drawer does not sit pinched between the drawer’s floor beam / top hat and the vehicle chassis.
The plugging out/in of the wire into/out of the sensor itself is quite straight forward. You do not need to disconnect the battery however you can if you prefer to do that.
You also do not need to drill holes – the holes are actually pre-drilled and there is a zip tie provided (the instructions need to be updated in that regard)."
