Talk to zfever http://www.zfever.com/ about nats removal and whatnot. We had a few members that had great service from them.
You can also talk to uprev.com about it.

Well from looking at the fsm for your year, http://www.xenons130.com/files/1979%20280zx%20FSM.zip, the wire that controls fuel pump 1 from 2 is Green/White.
Assuming you have the wires hook up according to http://forums.hybridz.org/index.php?/topic/38461-240z-260z-280z-turbo-swap-guide/, The blue/red -> green/white.
With this the ecu will control Fuel Pump 1
Revised units have date code of OK9B (February 2009) or newer.
Where did you purchase the alarm from?
I'll see what I can come up with searching around. 10k resistor in series on the blue wire in the antenna harness.
For the rust and corrosion issue, where is the relay located? Possibly a better place can be found.
For the relay connections.
85 Switched power from ignition (starter circuit). Most likly black/yellow. Use test light/multimeter to make sure.
86 ground
30 Goes to prong on solenoid
87 Fused 12 Volt constant
The ignition switch itself makes Acc/Ign.
The second black/yellow wire, does it just go back into the harness wraped in e tape?
Just reread what you wanted
Are the rest of the wires In figure N connected? Also the harness you have on there now is from what year?
You should have power at one pin of each injector when ignition is on.
You could use a simple relay for the fuel pump in two ways,
One way is to have it on whenever ignition is on, These are the numbers on the relay
30->> Fuel Pump+
87->>12 Volt Fused Constant
85->>ground
86->>ignition.
The other way is to wire is to wire it using the fuel pump signal from the ecu. This can be seen as Figure N here http://forums.hybridz.org/index.php?/topic/38461-240z-260z-280z-turbo-swap-guide/
30->> Fuel Pump+
87->>12 Volt Fused Constant
85->>ground
86->>Blue with red stripe
They would work if you already had lenses with removable h4 bulb. I'm sure you can piece something together from ebay for cheaper with replacment lenses. Still no cut off like a true projector.
A multimeter helps a whole lot, but heres a diagram for you. White/red - 12v Constant, Black/white - Ignition, Black/yellow - Start, Blue/red - Accessory.
