I spent 20 hours reworking the harness on the bench of my recently built 79 Rx7. One could assume that a 79 harness is a lot thinner to begin with. I only removed what I interpreted the gcr to allow and removed 8 pounds IIRC. I left speaker wires and such because I believe there is no authorization to remove them.

Hey Dick,

Did all RX7s come with stereos?
