Fiesta 5Dr Speakers And Wiring - Colours For Cutting Loom Cables?

[buzz234]

Hi guys,

im hoping someone can help...

fitting a new double din to a ford fiesta 2003 5dr, thats not the problem - the issue is with putting 6x9s in the back and either:

a) finding the speaker cable which travels to the rear doors in the loom cable (what colour are they?! for pos and neg) and then cutting it before reaching the doors and using a transformer plug to run extra cable to the boot for a parcel shelf.

or

B) runnign cable from the head unit directly to the parcel shelf. but again what colour cables off the ford connector (or would it be done on the iso adaptor for the head unit?...) are the rear Speakers (pos and neg?)

many thanks in advance,

B.
