to convert non-vtec "11F0" boards from non-vtec to VTEC, add: In top left quadrant:

• C60 - 1uF, 35v electrolytic (tantalum?) capacitor
• J10 - 0 Ohm jumper wire
• Q101 - A143 PNP switching transistor
• R201 - 10K resistor (Brown-Black-Orange-Gold)
• IC14 - 515 XHigh Side Switch MUST USE 5151's OR EQUIVALENT on this board revision. 5050s will throw VTS code.
• D11 - Clamping Diode

This is an evolution of the "1720" board design. Things are simpler, as is evidenced by the conversion having fewer components than the 02 D01720-1500 conversion. Automatic P06 ECUs have SK-5151 high side switches, just in different spots. Desolder them both. Use one for conversion, and save the other one. The A143 transistor @Q101 can be taken from Q28 or Q27. (Note: I've noticed that IPT bd. 11F0-1500 automatic does not utilize Q27 or Q28, you must use transistors from some other source.)
