Yes just fitted an AutoSparks loom to my 53 year old Land Rover. All cables of original gauge and colour coded. Loom cloth covered as OE as are terminations (mainly bullet) and back to back female connectors included where needed. The source seems highly regarded in the LR series 2 club and I certainly had no complaints.
I believe they can accommodate custom changes as well although this may mean a longer wait. Mine arrived in a little over a week. Let me know if you need anymore info.
