A Couple Quick Questions Before I build my DIYPNP
#1

Been searching for a couple night for info/answers to my questions and couldnt find solid answers. I am going to build my MS unit tonight and want to double check a couple questions that I have.
1. For the seq. injection.. After I solder the 10pin header onto the main board do I have to hook up jumper wires from the main board to the 12v and IAC on the seq inj board? I read your install write up and am a bit confused on that. I know that I have to jump the seq board to inj 3 and 4 in the pronto area which is linked to the 3/4 above inj2 on the edge of the main board.
2. On the 94-95 Miata Jumper Configuration it does not show that you need a IAC pull up. I read in a thread (linked below) that I do need one. Can you confirm that I do?

3. For the ignition set up, if I am running the stock ignition/coil set up, do I jump the board like this..?

4. If I am not going to set up my board to knock sensor can I omit the following?
Knock: C3, C4, C5, Q10, R22, R23, R24, R25, R26, R27, R28, U3, U4
Any/all help is greatly appreciated. Thanks!

1. I ran my outputs directly to injectors 2 and 4, not 3 and 4 on the output board. Make sure you get it right. AEM's EMS publishes the correct injector locations on the harness. I verified them. Check this to confirm cylinders 2 and 4 not 3 and 4 and correct order: http://www.diyautotune.com/diypnp/docs/sequential.html
2-4. Can't remember - sorry and I've got a 96.

1. yes, you'll wire the two outputs holes labeled 3 & 4, to the match holes right near the module. then youll wire the 3 and 4 hole near the other two inj outputs to th3 connector board.
2. not a pull up, but a diode, bottom right corner of the board.
3. no, on the bottom right corner where the pullups are, you'll jump op- to 12v and vr2 to 5v with the spare 470ohm resistors.
just follow this:
