Nissan 350z - G4 and PDM build thread

[BeallJK]

I'll open with that I'd rather keep all my questions / content to a single thread and hopefully this helps people follow along and/or helps solve their problems if they're similar to mine. 

Background: 2003 Nissan 350z running a Link G4+ and completely fed-up with Nissan OEM IPDM - especially the first generation IPDMs where the fuses/relays are rather finicky.  

Goal: Get the car running using the Standalone G4+ and two Razor PDMs and hope to incorporate a keypad for some control and using some of OEM controls.  

Question #1 - the car is running on the G4+ and has been since 2018.  I also have a G4x that I was getting ready to drop into another chassis (a separate infiniti g35) but would it be better to use the G4x with the Razor PDMs? 

Question #2 - Other than High Performance Academy (as I have done all their course work) is there another learning outlet that Link Razor PDM users are subscribed to, to further learn the PDM?    

Question #3 - is Pin 4 Ign Switch equivalent to an OEM 'accessory' stage? or 'on' stage? on an OEM key-barrel setup? 

Is it wise to mimic this configuration?   

My thought is to have a 3 stage latching switch on the key pad where the 1st push is 'accessories', the 2nd push is 'on' and a 3rd push would be off.   Then have an independent button that activates the starter while the button is pressed.

The main differences off the top of my head:  G4+ will be a bit more manual to setup in terms of the CAN, but not difficult.  G4+ doesnt send PWM aux outputs over CAN - only on/off.  But there are usually workarounds for this - for example if you wanted a variable speed fan you could send coolant temp to the PDM instead and do the speed control logic in the PDM.  G4X can accept a lot more different types of CAN inputs - analog, frequency, digital, temp etc.  G4X has PDM channels built-in so you can for example log currents and voltages of PDM pins in the ecu.

Pin 4 powers the PDM up, the PDM would need to be powered up for the keypad to work so there would usually be a hardware ignition switch or isolator/master switch controlling that pin.

Thank you Adam - 

Could I gather the brain-power of the group to critique my PDM layout -

Sensor +5v & ground #2  - (Pin 11 open) & (Pin 12 Ground)

 

Questions:

Am I forgetting anything obvious? And/or anything you’d do different? 

Can high beams & HID low beams run on a 20 to 25amps (via Power Output #4)?

Am I ok powering 6 ignition coils off Power Output 2 (three coils on Pin 1 and three coils on Pin 8)?

I would like to retain the OEM wiper stalk and OEM turn signal stalk to activate wipers / parking lights / turn-signals / hazards / headlights - is this the best way to do it?  (I am researching how nissan / if nissan ran the CAN bus through the stalk)  

• Parking lights (day time running lights) seem pretty straight forward
• Could headlights be run from a ADIO circuit to active a relay?
• Is there a way to blink signals/hazards with the PDM?  

All apologize for the newb questions
