I will love to see the final product!!!!! I will probably be your first costumer.

Keep me posted.

Thank you

Well in a moment of pure serendipity, I found a dual hi/lo trigerred relay kit from Fry's Electronics near my home. I figured out how to design the START & STOP functions to work using this kit. The relays on this board will control larger Bosch 30A SPDT relays, one for the START function and one for the STOP function. "Egor, quickly back to the lab we have work to do......"[I]

I really hope you will start selling these once you finish.

 

Keep up the good work Greg.

 

And I thought reading the schematics for a F/A-18 Hornet were crazy...

 

Haha exactly, schematics and diagrams with an F-16 make sense to me, yet I never thought I would have to think so hard with the Z lol. Cant wait to see how it works out, although I am sure it will be PITA to get it done.

 

LMAO

I hope this is a kit, i'll surely buy it.

 

Didn't go through the whole thread so sorry if this is a stupid question, but I want to clarify something.

Are you planning to use the clutch switch that has to be depressed before you start the car to kill the engine? If so, I don't think that will work.

 

ohh keep us posted!

 

Tell me why, please.

 

I spent most of yesterday working on wiring up the START/STOP button assy. I had to re-engineer the LOCK, ACC, and ON LED's as they were all originally common anode (+), as well as sharing a surface mount 1.8k current-limiting resistor, and I had to make ACC and ON common ground; the LOCK LED is wired seperately because it will get its low or ground signal from the factory alarm system. I had to place a bunch of resistors in series for the LOCK LED and those are hidden in the pigtail. I cut off the original modular plug flush with the bottom of the button (for clearance concerns in the console) and I extended everything out on a 9-pin Molex male pigtail and then finished it off with some heat shrink tubing. This will allow for more mobility when placing the control box, plus I think it just looks better.

Looks good.

 

If it works the same way as my BMW, which it may not, all the switch does is disable the starter when the clutch isn't depressed. Think about it, every time you push the clutch in and out its cycling the switch, but the engine remains running.

 

No, I'm not using the act of pushing the clutch in itself to shut the car off; rather with the clutch released there will be 0 volts at the gray/red wire at the clutch switch which will provide the appropriate low at Relay 1 of the control board (the STOP relay side). This will then allow the Bosch STOP relay to activate when the START/STOP button is pushed to shut off the car. This works because the 12 VDC that will be going through the ignition switch to the ON side of the harness passes through the normally closed switch contacts of the STOP relay. When the STOP relay is activated, the normally closed contacts will open, thus interrupting that 12 VDC to the ON side of the harness - the exact same thing as turning the ignition key from ON to ACC or LOCK.

 

looking forward to buying a set from you..keep going man!

 

Ah ok. I figured you knew what you were talking about, especially after putting together that schematic up there

 

I agree, it looks a lot better than the S2K button. It looks clean, as if Nissan meant to have it OEM.
