Sorry about the non Holden Question but you guys are the only ones that ever have the damn answers.... I've got a bit of a drama I need the SCHEMATIC WIRING DIAGRAM for both the 300ZX IGNITION SYSTEM( Amplifier and coil packs mainly but any of the rest of the engine schematic would still be helpfull) And the RB25 twin cam SCHEMATIC WIRING DIAGRAM..... Thanks to anyone in advance for any help.. My problem is I've lost power to my coil packs when I swapped cars with my engine.. The engine is an RB30 bottom end with an RB25 twin cam head on it.Trouble is it runs coil packs from a 300ZX so I'm not sure exactly what the wiring differences are between the two if any, but it would make it a hell of a lot easier to trace it back with the appropriate diagrams/help.... ANY IDEAS??????
