I'm nearly done with it just a bit confusing as to what to do with the last few pins on the board. OP+, OP-, VR2, IAC.
Does it look about right

not built one but would guess, op+ & - are for optoisolator input for triggering off a coil negative so can be left alone, vr2 would be a second vr input cam sensor ect thats the lm1815 circuit on the board, iac is usually for stepper type idle motors, are you using the stock idle valve as thats a pwm type valve.
3 bips wasted spark?

did you fit the 18k resistor in-line with the vr+ wire and set it up to trigger the main relay? are you fitting a variable tps to the car? and have you done the jumpers for the 3wire pwm valve?
