04ProbeGT, no way! I am starting with an PFC FCON from a 1987 RX7 Turbo and I have the harness plugs from a 1988 MX6 GT to use.
As long as you're using the harness from the 87 RX7 ZP4 thats the best harness to use as you only need to rewire the injectors as the rx7 runs 4 wires and the mx6 runs 2. If you know what you're doing this is a 2 min job.
All of my info on rewiring the harness came from the real hks mx6 harness. If you need a eprom chip let me know I still have a few.
I found its better to run a stock chip with only fc as apposed to using the fcd.
