The engine is built and ready to be installed. The 12A is out. My fuel tank is about to be sent off for EFI modifications. I have 90% of my parts. Now the fun part begins... wiring...

I have the complete harness, ECU complete with two relays and pressure sensor. The top relay is for powering the ECU and bottom relay is for powering the fuel pump? For the time being just to get it started and drive it around the block Im staying with the 1980 ignition. I will find a proper SE dizzy soon after. I dont need the dash front or rear harness? I'm thinking this is all I need to get it running...

*RPM signal - Could I just run a wire straight from the - on the trailing coil to the RPM signal wire?

*12v to the ECU - Run a fused + wire straight from the battery to the main power on the ECU relay

*Trigger wire for ECU relays - Run the switched + from the ENGINE fuse as the relay trigger wire for both relays on the ECU tray? It no longer carries the load of the fuel pump so it should be able to handle the strain of being used as a fused trigger wire. Right?

*Fuel pump - Take the "energized" wire from the fuel pump relay and run that straight to the floor harness using the stock fuel pump power wires?


Am I missing anything?I want to get this thing up and running ASAP. I hate being down a car, and Id like to start working on the RX8 soon. Any help from the SE experts is much appreciated. I have a hard time figuring out wiring diagrams sometimes so a layman's wiring diagram (MS Paint picture lol) would be great. Thanks everyone!

 

you should look in the SA manual, i would bet that the emissions control box has all of the wires you think you need.
