wiring from back to front (mach460)

[dutch]

So I installed my new wiring harness that I bought from a member here.. finally got the CD player working (mach460). Now I'm left with non-working speakers in the back. The new wiringharness had 2 or 3 plugs left that I couldn't put anywhere and I felt around in the trunk underneath the speakers and found 1 big connector with no wiring.

So my conclusion is that there must be a wiring harness running from the speakers/amps in the back to the dash to connect with the stereo wiring in the dash, am I correct?

second question, any got one of these laying around? :tongue3:

Look in the Classifieds at the cars being parted out. Someone might have one lying around form removing the Mach 460 stuff
