Microtech Alternator Wiring to avoid CAS Interference?

Alternator Wiring to avoid CAS Interference?
I have an S4 N/A that I'm putting an LT10 into. I'm in the final stages of buttoning it all up, but have a concern about the alternator wiring. The car has an FD alternator in it, so it needs one wire from the connector to the main fuse block, and the big 8 gauge wire from the (+) terminal on the alternator to the fuse block. I've ditched the 23 year old wires that used to serve this function, so I am now running new ones.
The question is, what should I do (what have you guys done) with the routing of these (+) wires to avoid possible interference with the CAS? Is the shielding of the Microtech CAS harness good enough that I don't have to care? If not, how far away from each other should the (+) wires and the CAS harness be?
Thanks!

I use aluminium foil.
I know it sounds dodgy, and it probably is, but i have been doing it for years and it hasnt failed me.
I put Aluminium Foil tight rapped all the way to each side of the plug and then heat shrink it.
On my own car the Cas wire runs directly under my 110 amp alternator, then beside my CDI Crane coil packs(2-3 cm away) and then in the cabin.
Like i said.
The microtech can tolerate.

Mine is the same way. I run my CAS wire right beside the alternator, complete with 1" unshielded section totally exposed aside from the harness cover. To make matters even crazier, my main + wire for the alternator runs through the same harness as the ECU and terminates at the aux fuse box directly under the ECU.
Microtechs are almost immune to noise. You have to do something seriously wrong to cause interference.
