Default MSPNP1 - Pin confirmation

Trying to power the mspnp1 unit outside the car, to test out some serial connection issues that I am having.

Just wanted to confirm that these are the pins.

Been having issues with connection, tried to flash a new firmware and I kept getting an error. This wasn't an issue before, but my car was put in storage for awhile and now nothing works lol

Info:
Windows 7 64bit
FTDI chipset USB to serial cable
Did the boot jumper thingy
MSPNP is out of the car

Port check:

<p>Was the boot jumper installed?&nbsp; What brand USB adapter?</p><p>Your serial comms appear to be garbage.&nbsp; If the boot jumper was installed, you need to replace your tuning cable and/or USB adapter.</p>

I used a piece of wire to short the boot, as for USB adapter, I originally was using this with no issues: TRENDnet | Products | TU-S9 | USB to Serial Converter which is a prolific chipset. After getting tired of trying to make it work, I browsed the msextra forums, and many recommended a ftdi base chipset for the USB adapter.

So I went out and bought this thing: SABRENT Model SBT-FTDI - Newegg.com

and still no luck. I considered the tuning cable to be bad, so I opened up the serial connector but I didn't see anything out of the ordinary.

<p>It looks like symptoms of a bad cable.&nbsp; The other option is that the bad cable screwed comms up so bad, the monitor on the MS1 chip is toast.&nbsp; If that's the case, the easiest solution is to purchase a new MS1 chip.&nbsp; They're cheap.</p>

Guessing there's no way to test if it's a bad cable or the monitor on the ms1 is toast?

I just want to make absolutely sure that my mspnp took a dump on me before purchasing another one.

Sorry to hijack, but this doesn't really seem worthy of a new thread. Is there any way to find out which pin is which? I bought a DIYPNP already built and I can't find a pinout anywhere. I mean I can probably figure it out if I look at a stock ECU harness pinout and then look at the board and all the documentation, but I figure someone HAS to have already done this. My car is a 96 manual with a blue board (3.0) DIYPNP.

I was going to write some pissy-mean comment, but it was actually just easier to link what you needed:

Update: Issue resolved

For whatever reason the mspnp's cpu was toast. Replaced it, and now the unit works flawlessly.
