Automatically process the Navi OK screen
We tried to make custom harnesses for a VW vehicle about a year ago - it was a disaster. It adds tremendous cost to the project and really adds no 'actual' value. In a low volume production piece like this it would easily double the price of the unit, as you have added costs for both parts (connectors, cable, etc.), labor (including the price of tooling), and R&D (finding, testing, verifying, quality control). In this instance, for the 08 sedan, you would actually need to seperate plug and play harnesses, one for the "OK" button that is actually a ribbon cable and one for the power, VSS, reverse, and ground. This may or may not be the same connectors used in the coupes, in the '07 vehicles, and the '09s. Nissan doesn't typically keep the same connectors for more then 2 years. From the looks of them, neither of them are standard connectors.
Soldering isn't permanent, and is almost as easily reversable as a plug in solution. As long as you have access to a volt meter you can't mess this up.
I have a slightly biased opinion about this point of view due to the fact that I was a professional car stereo installer for several years. We soldered every connection we made, whether it was a car stereo, an alarm, or a remote start. Like I said, as long as the installer knows what they are doing you can't really mess this up.

To those who have paid the test modules have been shipped. If you have not paid yet and want to participate please pay ASAP. We need feedback quickly so we can get these to production!
We had a limited number available to the first people who volunteered to help. A list of those people was in post 102 of this thread (https://g35driver.com/forums/showpos...&postcount=102)
OK, I've got it installed and it's working in my test around the block, over the next week I'll give it some more testing and make sure everything else works fine in the car.
a few notes I'll mention.
1.) The length of time to hold down the OK button is very short, it's 1 second or maybe even a tad bit less. In my testing I've acidentilly triggered it a few times already. Kevin, it would be nice if this could be a full 2 seconds before it gets triggered.
2.) At first I thought it wasn't working right because it's set to mode3 by default. in that mode you can't disable the bypass, you must wait 20 seconds and then the bypass shuts off on it's own. I ended up changing to mode1 so I can trigger it on & off.
3.) I set the navi OK timing to around 5 seconds and so far so good on startup. I did notice that if your in any other screen then the MAP screen then you still need to press the OK button manually. i.e. if when you start the car you were on CD, then the processing the nav screen won't work. you'll still get it when you end up pressing any of the navigation function buttons, i.e. map/route/destination/info. not a big deal, all I care about is the bypass.
4.) The instructions were a little difficult to follow at first, after a while I figured it out, but I think a good rewrite will help others, and some more pics.
5.) I had no issues after turning the car back on, no lights or anything. the only think I noticed was I lost my radio presets.
BTW, thanks to Kevin for the very quick callback & support on wiring! thanks!

also...which black wire is the ground? there are two black wire right next to each other.
i feel like a guy in a movie trying to disarm a bomb! ha ha ha
"which wire to cut...red or blue....red or blue!!!"

stanfna,
Both black wires in the harness are grounds, you can use either one.
The reverse wire should be an orange wire right in the middle of the harness - it should read 12vdc when the tranny is in reverse and 0vdc when not in reverse.
kring,
Thank you for the feedback. The delay time was played around with quite a bit while we were doing our original testing. It won't take much to make it a tad bit longer.
The point of Mode 3 is the fact you don't have to re-enable the VSS, it automatically does it after you quit typing in information. Some people may like the automated feature because it requires less button pushing, but others may dislike it because it does take the 20 seconds to reconnect the VSS signal. Either way, programming the output to different modes is quick and easy!
I'll take a look at the install instructions and see if I can clearify anything. We don't include pictures in our install instructions because they don't show up well, so we just post them on our support forum (http://www.kptechnologies.com/forums...pic.php?t=1019)

On the instructions Kevin, I noticed that the sheet included with the module does not have the correct locations of the wires, i.e. it shows the red/black twisted pair coming out of the center of the module, but the module has it coming out of the far side... not a big deal, but when you go to finish the production product it would be good to have them all line up.
For the directions, I think it would be easiest if they were worded something like this:
Black wire on KPT Module connects to either of the Black wires without cutting on the cars 60-pin plug. The two black wires are on the far end of the plug
Yellow wire on the KPT module with the fuse connects to the purple wire without cutting it onto the cars 60-pin plug. You will also connect the Red wire from the relay to this exact same purple wire. This purple wire is locaed at the end of the plug close to the two black wires. it is not the purple wire at the other end of the plug.
The Green cable on the KPT module connects to the white cable on the relay.
The Purple wire on the KPT module connects to the Orange wire in the center of the 60-pin plug on the car wihtout cutting it.
cut the light gray wire which is right next to the organce wire in the center of the cars 60-pin plug. Leave plenty of room to strip the wire and attach another cable, also allow enough room in case during stripping you accidently cut it shorter.
Attach the black wire from the relay to the gray wire you just cut at the end closest to the 60-pin plug.
Attach the blue wire from the relay to the gray wire you just cut on the side that goes into the car. so electric would flow from the car on the gray wire into the blue wire, then through the relay, out of the relay on the black wire and then into the gray wire at the plug.
Cut and throw away the green wire on the relay. it is not used. or Kevin, if this isn't used, it might be easier if you shipped it without this wire.

I do like your writing style, as I do realize I tend to oversimplify the installation process. I've been installing things in cars for as long as I can remember, so some of the little things seem so obvious to me - like cutting wires and leaving enough wire to work with.
Again, thank you for the feedback. As I revise the installation manual I'll keep your comments in mind and hopefully clearify areas that slowed you down.
Alright, so far so good. I'm moving forward with the plan to actually mass produce these.
The goal, most likely, is to offer one module that will process the OK button and allow programming while moving. It will include everything you need to make these features work, as well as installation instructions. The MSRP is going to be $99.99 plus shipping, with a group buy price of somewhere in the neighborhood of $85.99 plus shipping.
How many people would be interested in this module at this price?

I highly recommend this module!!! I have had it for one week now and it has proven to be very useful!
Anyone close to Birmingham...(or willing to drive to B'ham). I can offer my assistance in installing this in your car.
