MS3 or MS3X for IAC?
Stupid Noob Question:
I'm slogging my way through wiring a MS3/MS3X from DIY Autotune into my "99 with an 04 MSM drivetrain" project, and I'm unsure if I should be using the MS3 "pwm" pin or the MS3X's "Idle" pin? Is there any advantage (functionally) to using one over the other? My reptile brain says use the MS3 pin to save the MS3X's pin for some possible future use. Is that correct?
Thanks in advance-

(BTW, lol at "building the circuit".. My electronics skills were taxed at just soldering the pins on the DIYBOB!)

As Brain said, there's more than enough free outputs on the expander. You'll never use them all, so just use the expander idle output. Don't forget to add a 1N4001 diode with the banded side to 12V and the other side to the idle output (shouldn't DIY already have done it, not sure if they do).
