shifter cable interference?

[thebarber]

this was mentioned on echodrivers.com to me this morning and i havent looked in my engine bay yet to check, but how close do the shifter cables come to the header?

i installed a dc on the weekend and someone mentioned i should move/ziptie them out away from the header as they may be affected by the additional head of an unsheilded header

i don't recall seeing the cables near the header, but could anyone confirm/deny their location and whether an unsheilded header would affect them on a yaris (vs an echo)
