OMG CHILL WITH THE CAPS!!!

 

1) First, find the IGNITION POWER wire which is YELLOW/ BLACK, you will need to expose a 5-10mm portion of this wire to solder the RED wire from your SFC to. Do not cut this wire!.
2) Now find the RPM SIGNAL wire which is WHITE, once again, do not cut this wire, you need to tap into it by exposing the wire and making a solder join to the GREEN wire which comes from the SFC unit.
3) The first wire you need to cut is the VTEC SIGNAL wire which is GREEN/White. Make sure you leave enough wire on each side to join to. Make the cut and solder the end coming from the ecu to the YELLOW wire from the SFC, connect the other side of the GREEN/WHITE wire to the DARK BLUE wire from the SFC.
4) Find and cut the VTM wire which is colored BLUE/BLACK. Solder this to the GREEN/WHITE wire from your SFC. the other end of the VTM wire is not needed and must be insulated with tape.
5) Now find the SPEED SENSOR wire which is colored YELLOW/RED. Connect the end coming from the ECU to the PURPLE wire on the SFC and the remaining end to the LIGHT BLUE wire from the SFC.
6) Finally, cut the SENSOR LINE wire which is WHITE and solder the ORANGE wire from the SFC to the ECU end of the WHITE wire and the remaining end to the BROWN wire coming from your SFC unit.

Now that all the wiring is finished, you need to ground the unit and and reinstall the ECU. I found a bolt behind and to the left of the ECU to ground it to, it was the grounding point for another wire as well.
Replace the ECU and the metal panel, securing them with the 4 bolts.

 

 

I thought I gave you the instructions....
