Engine wiring loom?

Next issue. I've been getting some higher than normal revs at idle when the engine is warm (sitting about 850rpm instead of 600 or so) and my mechanic said the issue appears to be the wiring loom that connects to the coil packs under the rocker cover.

Apparently heat has deteriorated the plastic casing and is causing some signal problems to the spark plugs. He patched up the lead and the engine tends to return to normal idle more often now, but he suggested to get it replaced.

I contacted a mob (suprastore.com) and the guy told me these looms don't exist any longer and the fix was to get a new set of coil connectors and rewire the loom near the coil packs and solder the connection.

So, question is, does anyone sell these wiring looms and is this suggested "fix" the way to go, or is there a better solution? Also is there a way to rehabilitate the loom cover to protect the wiring?
