5 seconds should be fine, too. Based on what turbo said, I think 2 is the minimum before the car initializes and starts recognizing the button, but I see no reason why 5 wouldn't work. I'll take one of the older ones and give it a go. I'll PM you...

EDIT: I removed my first guess at the pin connections to avoid confusing anyone...

Scratch that. I'm thinking that's not right at all. Turbo, nater, any suggestions? ;)

How about this?
  • TR-7 Black to VPS Black (pin 1)
  • TR-7 Red to VPS Blue (pin 13)
  • TR-7 White to VPS Green (pin 5)
  • TR-7 Green to VPS Gray (w/Red stripe) (pin 11)
Is that right? I'll stop guessing now until I hear from the experts. :)

EDIT: Updated...

Someone PM'd me and I figured I'd just answer publicly because I didn't want anyone to get the wrong idea.

Any frustration expressed in this thread is directed 100% at myself...it's not the first time I ran with an idea spending lots of time on it (fortunately this wasn't that much time) and found out there are other options, or just no interest. I get overly excited (because I truly love doing things like this) and start spending time on it without thinking all the way through. It's a bad habit that I can't seem to break. The fact is no one forced me to spend time on this. Someone asked for a solution, and I ran with it. Bottom line is, I think it's great there is already an option out there for a decent price. For the number I would sell, and the time I'd spend making them, it really would be a losing proposition for me for such a cheap part.

Let's hope the SOC gauge doesn't turn into the same thing, because that project I did spend a lot of time...and now money...on. heh

Hey, turbo, I know how you feel. I don't blame you for dropping the project. I'm perfectly OK with using this off the shelf solution. I'll even write it up for others who want to follow in my footsteps. But I could use some help with the wiring. Your original schematic doesn't list what the pin outs are for, and I don't know much about how to read the circuit design, so I'm guessing. If you could pretty please take a quick look at the pinouts on the TR-7 and suggest which ones to connect to what, I would really appreciate it.

Thanks for taking a look at it in the first place!

I just looked at it and I got to say, it's confusing to me. Maybe nater can help. I'll look again this evening.

OK, just in case he doesn't get to it, can you tell me which pins do what on your original diagram? Pin 1 seems pretty clear to be ground. Is pin 11 the +12v input trigger? And pin 5 the button press output? Is the output pin positive or negative? Based on my interpretation of the TR-7 functionality, I'm hoping it's a case of connect the +12 input to the negative output...

Thanks man!
