Right on brother!
I've been trying to figure out where I could reroute the heater hoses so that they aren't smashed up behind the valve cover with the wiring looms. No easy solutions have jumped out so far.
Actually finding decent silicone hose with 5/8" and 11/16" ID in the UK is harder than you might expect too.
As it was I've just rewrapped the sensor loom and put some more plastic tubing around it. And crossed my fingers.

 

Thought I'd give it a go...

 

I must say that my RHD engine bay even looks again somewhat different tha yours.
No wireloom stuffed at the back of the valve cover. Where you have one grey connector left of the dipstick (in the pic), I have both connectors located. Might be an update thing.
And right in the pic, just before the A/C par that I can never name (condensor?), you have some ort of mini brake booster thing....what's that?

 

Wow that's cramped. Now I see why you missed the rearmost bolt.

Which pic and side are you talking about Roler? First pic, drivers side has the cruise control solenoid parked beside the brake booster and master cylinder; same pic on the passenger side has the A/C canister thing next to the ABS pump.

 

Yep. The black canister is the A/C accumulator. The thing in front is the ABS control unit - on the opposite side of the engine bay to the rest of the braking system, obviously!

The other electrical connector is there, I disconnected it and moved it behind the auto box dipstick to take a bit of tension out of the wiring loom. That allowed me to yank the loom an extra couple of mm higher to get the valve cover over the rearmost rockers.

If I have time for a project next summer I might just give the Jeep a bit of bespoke DIY wiring and hosing to tidy it up. In it's current, stock, format it's just a matter of time before the routing causes major problems - in my layman's opinion.

 

Ah, the ABS thing. No wonder I didn't recognise. Don't have ABS.
And same for the Cruise control solenoid. Don't have that either.
