There are four wires that are included on the harness to the 2D controller. I got a great tip from the DSMLink forums to use the ECU wiring harness when wiring the kit. Stolen from VFAQ, here is the diagram for a 2g ECU. If you have a 1G go to
www.vfaq.com and find your diagram under electrical > SAFC install.
Yellow: MAF signal wire (3 on diagram)
Red: +12V switched power (opposite pin from 7)
Black: GROUND (6 on diagram)
Green: Positive wire to pump
BOOST SOURCE:
The last thing to hook on the controller is a boost source. I tee'd off of a boost source in the engine bay and routed some line through the firewall to ultimately mount my 2D controller in my glove box.
WIRING ON THE PUMP:
It's pretty basic. One black (make a good ground) and one red (goes to green wire on 2D controller harness).
Lastly, fill up the tank! Play around with the amount of methanol you need mixed within your system. I started with a bottle of HEET and the rest with 50/50 smurf piss bought at ACE hardware.
