What info do you need on the wiring? Seeing as I wrote up the 88-89 wiring over at pp and have converted a lot of the harness. Also what harness are you starting with?
As for buying the database its never gonna happen it was hosted on a private server. Its best to just understand pp will never be back and that info is gone for good. Well you can still do some web crawls of the site.
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.
