Hello, All
I am having some wiring problems with my CA18DET swap into my 510. I have basically stripped everything that I could IE. IACV, ECCS and a couple other items. I have been using the CAN AM box that people usually run on the Datsun forums.
I have a key power source that is jumped through a relay that touches the run wire. I cannot for the life of me get the fuel pump to turn on (Black pink wire) or get any signal wires to turn the ecu on.

Here is how my wires are run / what I have hooked up:
Orange: Starter Solenoid
Black Gray: Run
Black Pink Fuel
Injector Wires / Dropping Resistor (Do these need grounds? If so, at what point?)
MAP wires (Four green / black yellow as appropriate)
White: Knock Sensor
Two yellow: Throttle sensor
Two light green: Throttle sensor
Two blue: Coolant temp
Pin 32/58: Jumped for ECU Backup
Any ideas? I will put pin locations when I get hm.

Here is the link for all the wires and it all lines up perfectly. If someone wants to highlight the basics or how it needs to be run that would help a lot.

To those who stumble across this post...

Check the ground wires. Apparenlty this ECU is pretty finicky when it comes to the grounding wires.
