EZ Wiring Mini 20 Circuit Installation

Couple of questions please:

. think there are at least 3 looms in the car ?? Engine bay, dash and rest ?

Can you just replace a portion ?..lets say just the engine bay.
Rather than recreating all...why just not run new wire and use existing
connections ?
Can you put the fuse box under the bonnet vs under the dash ?
Where do you buy new mopar connections.

Great thread...didn't know mosquitoes were bad in Sweden :)
