My 280Z has a D6F4-01 distributor. The three leads at the end of it's harness are all the same color of blue, but I at least have them marked as to where they go from when I tore the engine out (they go to the terminal block near the front of the left fender well). My problem is the female half of a bullet connector that leads to a small condenser (which is close to the terminal block for the three blue distributor wires) that I marked "Dist" at the time I pulled the engine. I need to know where the other half of this wire would connect to the distributor.

I'll go check right now, but i'm pretty sure that wire off the condenser just goes to ground

Okay i just took a look, the female condenser wire (blue) connects to a black wire. I have mine wrapped up with plastic sheathing so i can't tell you where it leads to, but i think it was just grounded under my ballast resistor

The 1976 wiring diagram seems to indicate that it goes to ground on the female bullet connector side. However, when I pulled the engine to have it rebuilt, I marked that female bullet connector DIST. Could it have been grounded to the distributor body? Should it have? The original owner of the car did some pretty messy wiring, so it's not always clear which wiring was original and which he had altered. For instance, he had the yellow wire for the BCDD hooked up to an electric fan in front of the A/C condenser.

Well i'm not sure it matters where you had the condenser mounted to as long as the wire is grounded somewhere, i had to completely re-do my wiring because my car didn't even come with harnesses'

I grounded mine under the ballast (bolted ground to body) to clean up the engine bay a little bit.

As for the Bcdd / electric fan thats strange.. its possible the bcdd failed and no longer works so the PO used its wire for the fan.. but im not exactly sure if its a constant 12v while running or not. You can keep it unplugged and it won't harm anything, you'll just have a smelly exhaust

Just pored over the wiring diagram again. It's apparent that it really only needs to go to ground. Yet another place to clean up the P.O.'s questionable wiring skills.

Thanks for your help.

I also think I'll connect the BCDD to the yellow wire as it should have been before, and see if I notice a difference.
