Probably connectors. Check front and rear. Maybe a rear was never plugged in correctly and came out (doubtful, but ya never know).

Below the front right foot mate lots of cables are going backwards from the firewall , wity in these cable is a connection with splicers which is broken or rusted that causes initially intermittent and later on permanent break fault ( 3 amigos hdc , suspension , and special program off faults)

here is a link which is not very clear but enough to work on !!

I've just been down the rabbit hole of pulling out the CJB, fixing the sunroof drain line (had to put in a new line from the A-Pillar down) and of course, buttoned it all up. I found this thread on the Disco3 Forum. Super helpful to visualize, for me, the process:

Make sure relays are off the CJB. That'll give you some more room.
Start by laying in the footwell looking up.
Put the box in 90º-ish opened up to the inside of the truck
1 plug red
2 plug green
3 box in position
4 plug-in bigs
5 plug down (green)
6 fixed box

Once I had this in my mind, it took me about 30 minutes to hook it up and have the CJB mounted. I did take a few test runs.
Now all I need to do is repatch some wiring that has corroded and dry it out. And troubleshoot from there. Yay.
