The Split Second Controller is use to control additional Port Injection injectors. It uses MAF voltage and RPM to know how much to spray when. The controller is programmed via com to usb cable. It's kinda old school tech but it works well and is much more reliable then meth.

I will not be getting into the software side of this as most don't need to know this as they won't be tuning their own car. Here is some good info on that though.
Wires:

1234 - These each go to the far left side of the coil plug. It does not matter which plug. You will be tapping into the wire. Mine has a plug on it from previous install yours will probably be bare wires.
6 - This needs to be fused 12v+ ignition on so find a fuse to tap that is only hot when the car is running. Use an add a fuse to make it easier.
7 - Ground
8 - MAF Signal - This will tap the MAF signal to be able to read the MAF voltage
1234 - Here is a pic of where you want to tap , circled in red, you will solder 1 of each of those 4 to each coil connector far left wire. You can either cut the wire and re-solder if that is easier or be lazy and trim some insulation, solder and wrap in electrical tape. It's up to you but be aware if you mess it up you're gonna have a bad time.

8 - MAF - Here you will want to tap the middle MAF wire. This wire will output 0-5v MAF voltage

The rest of the wires in the harness plug into your PI injectors. Please check the video linked for testing info.

Side Note: Take your time, do it once, do it right. If you want to be fancy you can use weather pack connectors to make it so you can removed the unit easily. I am doing it this way as I incorporated it all into the harness when I redid it for my build.
If you buy the SP63 plug and play harness, here ya go.
SP63 - Harness
Red - Plug into existing coil pack wires
Blue - Plug into coils
Green - 4 wire coil signal goes to "1234" in the above picture
If you bought it all second hand and don't have the right connector go here. Otherwise you can solder the wires together.
