280zxSheik Posted April 24, 2015 Share Posted April 24, 2015 I'm trying to incorporate my tpi harness into my 280zx chassis and need some direction, should i be use the 280zx's original engine control relays? If so which relays? Do i need to use a gm relay center or buy a pricey aftermarket one? What can I remove from the tpi harness? What do I no longer need from the datsun original wiring or circuits? Can I eliminate the tpi fuel pump wiring and just keep the datsun stuff? How should I run the electric fans? What about the charging system, starter & how can I rear mount the battery?
