Zeal aux Inputs and Outputs

I'm finishing up my MS2V3/Zeal build and can't seem to find any info on the inputs/outputs.
Can I just run IN1-IN4 to any of the free JS ports on the V3 board? And the corresponding OUT1-OUT4 to SPR1-SPR4?
Are IN1 and OUT1 part of the same circuit, as if I built the circuit in proto?

And what about Idle? Also, I ran IDLIN to Bottom end of R19 and IDLOUT to Banded end of D8. I've noticed that D8 goes to Pin 30, but what do I select in TS to select that as my idle circuit?

Thanks,
Alex

Maybe I can clarify my question.
I am trying to figure out where to jumper the inputs/outputs on the Zeal card.
Firstly, are In1/Out1, In2/Out2, ect connected? Are they what you jumper JS and SPR ports if you were going to build your own relay output circuit?

Also, in the outputs options I am a bit confused with the port labels.
IAC1 = JS0
IAC2 = JS2
PA0 = JS11

Would I jumper IN1 to JS0, OUT1 to SPR1 (Pin3), and select IAC1 in TS?

Last, I build the Idle circuit per DIY's instructions, so I believe Pin30 is my Fldle circuit, but I haven't seen where to select that as my idle output in TS. Does that wire simply go to one side of the BAC, and the other is 12V?

Thanks in advance,

Alex

If nobody from DIY comments or asks on this, then I'll take a look when I get a minute.

Thanks muythaibxr,

To help clear up my question any further,
I followed the build process according to DIY's instruction.

On the Zeal card:

IDLIN jumpered to Bottom or R19
IDLOUT jumpered to banded end of D8

I still haven't been able to locate in TS where I select either of those as me idle circuit.

I have "PWM warmup" chosen in Idle Control setting. I'm just unsure how the 'squirt knows what pin to output to. I just seems like every other mod I've needed to jumper something somewhere to make sure the right CPU input and pin output are selected. I followed the directions DIY and the megamanual stated, so if that's all that's needed, I should be fine.

If anyone can answer my input/output questions, please chime in.

Thanks

I got a response DIY. On the Zeal board, IN# is jumpered to JS#, OUT# is jumpered to SPR# and pin 30 is the default idle output of you follow the DIY instructions.
