Hey all, I'm dropping a 280Z FI engine in my 240z and I need some help on wiring it up. I know of the ones that all plug in on the intake manifold, and the 2 that go to the battery, and of course that obvious one that plugs onto the computer unit, but there are a few harnesses that plug somewhere under the 280Z dash, and I need to know what function those serve. Does one plug into a switched power source via the ignition switch? I can't find my #$@$ manuals, if anyones knows please help!
