for starters i have never done a w.i. system other than on grand nationals which were much less involved than this system.

in the hfs3 instructions it shows a red wire the goes to injector+ a green that is injector ground signal, and a blue the wires into the maf(optional) in this same loom are other different colored wires that i can not find where they go in the instructions. also the jetting is throwing me off a little. I'm running 15 psi through a f1a pro charger the car should be right around 900 hp to the tires

Here are the functions for the wires of the grey connector. (minimum connections to get you started)

1. The red wire is responsible to switch the system on.
2. The green wire picks up the fuel cutty cycle signal.
3. The blue wire is only required if you want to trigger the system by boost.

Here the addition wires of the grey connector if you evolves from the basic.

4. Orange wire: map switch/failsafe signal to your ECU (if applicable)
5. Yellow wire: addition 0-5V input to alter the flow by +/-15%
6. White, brown and black. Relay output for failsafe.

If you want additional information, please go to the www.aquamist-direct.com to download the HFD3 user manual. Click on the 806-063 (HFS3-v3)

There is a guide line within the link or the user Manaus recommending the correct jet/jets to use.

Approximately 1-1.5cc/min per BHP. (M50/W50)

BTW, the last inside back page tells your the function of all the connectors.

thank you very much. i realized that the wiring diagram for this plus was broken into 2 parts for the failsafe function and injector signal.
