I don't know why you would think this is spam? It wasn't intended as spam at all. I have never dealt with Megaupload and didn't understand what it was or how to use it.
I have figured it out since that post. I've been a car guy all my life but not a computer guy. Forgive me.
I understand the gas pedal wiring and what the wires go to but the section just below that part of the write confuses me a little. Please help.
Let me know if I am interpeting the directions correctly.
The abreviation n/a is used several times. What is n/a? Probably something simple that I missed. Sorry
and last the obdii port
port ecu personal --------------What is this?
4 b n/a ground --------------- ground to the chassis??
5 b/w n/a ground ------------- 5 b/w ground to chassis?
6 l to 94 l n/a ---------------- 6 l to 94 on the ECU plug?
7 pu 85 lg n/a ---------------- 7 pu to 85 on the ECU plug
8 g/y n/a ign sorce ----------- 8 g/y to any 12v ignition source?
15 r 86 r n/a ----------------- 15r to 86 on the ECU plug?
16 r/w n/a 12V + ------------ 16r/w to 12v constant on?
Do I have these correct?
What remains from the ecm....
1 b ground
111 gy/l from output from the ecu relay ---- Not sure what to do with this? Do I connect 111gy to the stock S14 ecu relay? color code for that wire?
115 b/w ground
116 b/r ground
109 w/b ign sw
121 r/w 12+ constant
All of these come from the f3 plug and

I really couldn't understand your post from before, and I have as much trouble understanding this one too but I'll see what I can do.
the MEGAUPLOAD link is to a file that you should download if you are doing this swap. It is a .ZIP file, so if you are using an older operating system like windows XP you will need to download and install the program WinZIP which is available at
WinZip - Windows Zip Utility - Zip Files, Unzip Files to be able to open the .ZIP archive. Alternatively you could use the program WinRAR as well, which could be found at
WinRAR download and support: Start. If you have Windows Vista or Windows 7 you should be able to open the archive just fine.
OBDII plug wiring little more explained
PIN location wire color what it does ------------- where it goes
4 black ground --------------- ground to chassis
5 black/white ground --------------- ground to chassis
6 Blue CAN Line H ---------- Pin 94 on the ECU plug
7 Purple CAN Line K ---------------- pin 85 on the ECU plug
8 Green/Yellow ignition ----------- 12v Hot IN or ON Start
15 Red CAN Line L ----------------- Pin 86 on the ECU plug
16 Red/White 12V + ------------ to 12v Hot at all times (Constant 12v source)
For Pins 6,7,15 you splice them to the ecu to their corresponding locations.
Pins 4,5, you ground to the chassis
Pins 8 and 16 you connect to the corresponding sources.
This is the most that I can help you with as I am not as familiar with the wiring diagram on the 240sx itself
