p510psi is correct you don't need all that to get the engine working but you should have at least the following 1 x Relay for the Fuel pump (don't drive it from the ECU directly ) 1 x Relay for the Fan same reason - assume your ECU is driving an electric fan 1 x Main ECU relay - that can drive all other circuits I started with a 260z which has more modern style electrical circuits (sort of Nissan went part the of the way) and therefore already had an ACC relay for the ACC circuits. But like the 240z full current passes through the combination switch for hi/low beam so I am rewiring the heads to include relays. I will add an IGN relay and then all the normal EFI relay, Coil, ECU, Fuel Pump and Fan. Things like the O2 power, dropping resistor power etc will come off the IGN relay. Anyway sorry for the slight thread hi -jack I will post up a diagram in a new thread of the changes I make so others can see what I have done (when I do it lol) Cheers Mike Excellent work. Any update on this project? How is it coming along? Off-topic question: how does one subscribe to threads so one can receive updates through e-mail?

An awesome resource. Thanks for sharing.
