dears good evening am new member here seeking your kind help i am building a RX8 2004 i have already installed 1jz single turbo but the electric man cannot start the engine because of diagram he is so stupid and dont know what to do kindly can anyone help me to know the harness diagram so i can make the harness ?

 

Better get consulted with the nearest garage for more information

 

What ECU are you using? This isn't really a trivial problem because the RX8 ECU doesn't know how to operate a 6 cylinder boosted engine, and the 1jz ECU won't know how to operate the dashboard, so you need some kind of mixed system, a bit like the V8 guys have to do. Not sure I can help directly, but search the LS V8 swap threads here?

 

the best thing you could ever do, good luck with it all.
