Ok I have a Zeitronix wideband o2 sensor controller but I think this can apply to anyone who has hooked up any wideband o2 controller. I am splicing the harness for the controller into the ECU wires and I have no clue where some of them go.

These are the description of the wires for the controller that I don't know where to connect:
1.) RPM Input(is there an RPM signal wire I can splice into at the ECU? where did you get your RPM signal from?)
2.) Throttle Position Sensor(do I use D11 which is TPS Signal, or do I use D20 which is TPS 5V?)
3.) User Input 0-5v(what the heck does this mean and where does it go?!)

Also the Simulated Narrowband O2 Output, I spliced that into D14 on my ECU harness, is that where this is supposed to go? I believe this feeds the ECU a signal to avoid a CEL, is it out to just splice into this or should I cut the wire and connect it directly, or am I even doing it right?

1 and 2 can be found on your ECU. Find a pinout for your ecu. Can't help you with the others although there was a post very recently titled like "plx wideband help" or something like that. I think they were talking about simulating a narrowband, try finding it..

You might need an MSD tach driver, part # 8912 or 8913, I forget which.

User input is probably any analog signal you want to monitor. Say you have an electronic EGT gauge and its minimum value is 600f and max is 1800f (not real values! just for example). You would set 0v to be 600F and 5V to be 1800F and the unit should do the math to calculate volts to Temperature accordingly.
