Bought a Red Devil River USB ALDL connector last year to program my son's 95 Camaro LT1 engine/tranny swap now in his 37 Chevy. Using CATS WinFlash last year everything worked fine. This year couldn't get the laptop to recognize the connector. Learned that it was the 4 pin female USB connector mounted within the 16pin ALDL connector.

Wanting to get the flash done I just cut and soldered a USB cable with male end to the connector. PC now recognized the connector...but when I try to copy the bin to the laptop, it starts but stops with the window message: INCORRECT MESSAGE SENT

Here is the WinFlash definition:

INCORRECT MESSAGE SENT – This error message indicates that the message that was actually sent to the PCM is not the message the program is trying to send. This indicates that there is a problem with the RS-232 to ALDL Signal Converter or the connection to the PC or there is some local source of electrical noise interfering with the communications

To make a long story short I found these on ebay:

Also attached a picture of the inside of my Red Devil River connector...wondering if I could just swap out the converter adapter? Would R/R the resisters.

1) Since I already have the bench PCM harness with ALDL connector...could I use the Moates 16 ping connector for $30?

2) Any instructions out there on how to make my own ALDL to USB since I already have the parts

3) Who sells another cable at a decent price.

Thanks
