Heh heh. I can't weld for spit but I'm a whiz with a soldering iron!

The circuit is based on a Maxim MAX233 IC.
Circuit

I used a 233 instead of a 232 - fewer external components.

The '8062 ECU is 160 baud only, not 8192 baud.
Mode select does nothing either. The only connections needed to the circuit shown on the ECU side are ground and "M". M says 8192 baud data, but I connected it to the orange wire on my harness that goes to pin "E" on the diagnostic connector and it works fine (at 160 baud mind you). I used vampire-style wire taps. The other end of the device is hardwired to a long shielded male 9-pin serial cable.

I think I have an extra MAX233 chip. I ordered them as samples from Maxim (the circuit manufacturers, not the mens' magazine!) so they cost me nothing. It's built on a small piece of perfboard, wired point-to-point with thin wire. A bit tedious but not impossible. I used a wirewrap IC socket (which has nice long leads) so as not to overheat the chip while soldering.

The 5 volt regulator gets power via the serial port from the DTR and RTS lines (so the circuit is only "on" when plugged into a PC). CTS probably isn't needed since it was supposed to be used for 160 baud data (but as I said I used the line for 8192 and it works fine).
