Default Dual derale harness

So i purchased the racetronix dual fan harness. it doesnt come with instructions and for the most part its pretty simple. I just wanna ask the question incase im wrong..lol..So the harness has 4 total wires that say "trigger wire"...2 of them are + trigger wires and 2 of them are - trigger wires. Im gonna use the factory trigger line to get these suckers to work. The factory trigger is a ground correct? If so does that mean i only need to wire in the 2 "trigger" wires from the harness that are labeled "-"?

How is this forced induction related, and why don't people call manufacturers first when they have questions about their products?

Yes, the PCM grounds the relays for the fans, so the - wires will go to the PCM.

99-02 F-body typically use the FNWH-006 with factory PCM if both fan motors are the same wattage.

Right but i had already received the FNWH-004 harness and i would rather make this work instead of sending it back and waiting for the other harness to get here. Thats why i was trying to figure out what to do with the other wires. Im on the racertronix forum but all i seem to find are posts about the -006 harness.
