Throttle body wires are sensitive i believe if you messed with them for a quick disconnect. Brian, lightningguy on here mentioned something about it in his false firewall delete thread.
So throttle body wires were fine etc. My issue is that when I removed the all the engine and BCM Relays and fuses it got rid of the signal for ecu you to turn on. So I am now going to add a light on my dash so I know when the ECU is on. Also have to trick it somehow and get a signal to go to turn on the ECU which will be this weekends project
and hopefully she will FIRE!!!

I completely removed everything if u remove ac meter amp your stock cluster gauges will stop working. I am using my own 6 inch tach and gauges and I wired up my own circut and switch for the car fused and relays only thing on the car wiring wise that is OEM is the Engine Harness

Looking through the wiring schematics, that's all I could come up with, sending out signals. Was planning on removing stock gauges anyway, thanks man

and hopefully she will FIRE!!!"Of course the install was not without it’s hurdles – but what on the car this year hasn’t been a biotch! We discovered a major hurdle a few weeks back. Apparantly Nissan in their infinite wisdom decided that the alternator should not work if the factory cluster is unplugged. Ask me how I found out! Thanfully I was able to limp it back to the shop. I turned to some buddies who race their Z for help. They are running a Bosch Motorsport cluster on their race car, so I had a feeling they had enountered this same scenario before."

Thank you for the info my problem is ECU checks for the relays being in the circuit before it will start engine, so we just need to fool the ECU to think there are relays there since I removed the OEM Ones
So everything on my car is working but I think the ECU is fryed. SO look for one to test and a few prototypes in the making for 350z and Track use or DD use subscribe for more info!
