Audio Systems: 1995 chevy, chevy suburban, channel amplifier

for Wiring Diagram for a 1995 Chevy Suburban LT K1500. The rear door speaker wires do not directly match with any of the colors on the radio harness behind the dash. So where do they connect it the chain?

Go to page 7 above and you will find all the wires listed.  

This vehicle has 6 speaker wires; 2 up front and 4 in the rear. The rear speakers can be paralleled if you do not have a six channel amplifier.  Does this solve the problem?  Let me know if you need more.
