Does any have the the wiring scheme for V-tec? I have the wiring diagram for the conversion from EF to fuel injected. I don't have a diagram for V-tec. does any one have any resources.
Wiring conversion for DX/Standard to SiR

Radiator fan control B4 B4
Tandem valve control solenoid B2 - Remove
CKP P C1 B10 **Move existing wire from C1 to B10 (orange)
CKP G C1 B12 **Move existing wire from C2 to B12 (white)

Sensor voltage C13 C13
Sensor ground C12 C12
MAP C11 C11
Map sensor voltage C15 C15
MAP sensor ground C14 C14
* When switching to port injection, an injector resistor box need to be wired in also becuase of the different style injectors now used.** Another way to do this wiring would be to move the existing wires at C1 and C2 to the cylinder sensor (blue/green and blue/yellow) and run two new wires from B10 and B12 to crank position sensor (orange and white).Depending on the manual you are using, the numbering of the individual wires on the connectors varies. To use this chart, hold the plug in your hand as though you are going to plug it into your face. The clip that holds the connector in should be pointing up and the wires pointing away from you. Below is the numbering sequence that goes with the above chart

Run a wire from the Knock sensor to B19 (Red/Blue wire), VTEC oil pressure to B5 (Blue/Black wire), VTEC solenoid to A8 (Green/Yellow wire), Second O2 sensor to C8 (Solid white wire)

well i dont even care anymore....
i just correct them... its kinda inmature to start a flame just because he its not all that knowledgeable into hondas

doesnt nesesary a swap needs to be in process.....
i spend 4 months collecting info before i even dare to do my own swap.... hes probably searching all the info he can , so when it comes down to do it, he will have the less complications possible (wich if thats the case hes being a lil smart)
and while hes diggin info he will learn that its not V-tec , or Vtech or V tek.,.. its VTEC.... and technically its not VTEC ( its VVTEC , Variable Valve and Timing Electronic Control)

actually,
it's VVTLEC, since it's Variable Valve Timing and Lift Electronic Control.
also, it can ba called "v-tec" since it is written like that on honda air boxes
most of us just never see our stock airboxes for very long, or they don't ever have v-tec on them, since we buy cheap-*** cars.
edit- sorry keith just correcting a little mis-information, since the question has already been answered
