I was told this is an MS2PNP but apparently it’s DIYPNP?

Sorry for my lack of knowledge on this. I’m just getting into this tuning world. I’ve read about every thread on this but I just can’t get a clear grasp on it.

Ok back to the main issue then. That separate board should handle the alternator. I can't make out the pictures of the spaghetti. What is VR2 connected to?

That's DIY's assembly instructions. VR2 is your cam signal AFAIK. 3H should be correct. Make sure the pullup resistor is in place and jumper settings are correct

Cool. I’ll double check the assembly.

So it looks like the pull-up for VR2 is installed to the 12v. From everything I’ve read it should be 5v right? It ohms out at 466 so that seems okay.

Hot damn! I switched that resistor over to the 5V instead of 12V and she started right up! I need to get some things sorted out but it's running now. Thanks for everyone's input.
