evildky Posted November 25, 2004 Share Posted November 25, 2004 lol, it's a pretty easy swap, but out of the blue it seem kinda scary after you get done you'll laugh at how easy it was the instruction used to be stickied here, guess you'll have to search the archivres, trust me everything you need it here Quote Link to comment Share on other sites More sharing options...

evildky Posted November 26, 2004 Share Posted November 26, 2004 from an old post by moby did the install in my 73 240z last year and it went smooth, only have to connect a handfull of wires. Use the turbo EFI wiring harness and then connect in the few signals according to the wiring chart in the turbo swap FAQ. One for fuel pump relay, one for switched power to ECU, couple for ECU power, start signal hooked to starter solenoid wire so ECU only gets voltage during cranking otherwise you will run really rich all the time. Its about 7 wires. Ground the inhibit so it will start. Notice there are two YW wires in the same connector, so get the right one for the coil/ignitor. Did you guys see this in the turbo swap FAQ, if not pass on the info to the next guy. Good luck. Your BW wire on the 240z is switched 12volts. As mentioned your starter solenoid wire is only on during cranking for the start signal back to the ECU. let me know if you have more questions. You need to get a Haynes manual for '79 to '83 280ZX. This is the one with the red cover. Look on page 252, this is the wiring diagram. You will see 3 plugs labeled "1,2,3" with circles around the numbers. This is at the lower left-hand side of the page. The wires are as follows: Plug 1= BR 12v power source. Positive G 12v power source. Positive Plug 2=Y start signal (+) GL ground for inhibitor switch YW speed sensor (not necessary) Y A/C signal (+) YW coil (-) (must use ignitor) B fuel pump ground if using modulator Plug 3=LR fuel pump relay G ignition .signal (+) for air regulator W not used Y not used BW ignition signal (+) Quote Link to comment Share on other sites More sharing options...
