It may well be OK, without knowing what the circuitry is I can't say. If you're not good with SMT but want to build your own then you can get a through hole module from FTDI and substitute the SMT comparator with a leaded equivalent.

I had a look at the circuit, I may have some difficulties tryin to build it cuz I'm not too savy with SMT building, lol. Can you comment on this cable? 12 pin to USB interface.
I have now published my design for a USB interface for Suzuki ECUs. Main features are: Adequate isolation between PC and the automotive supply Automotive quality components, fully protected against noise and power surges Industry standard FTDI USB chip handles the non-standard baud rates. Complete circuit fits in a short J1962 backshell (with a little filing). PCB designed to ensure compliance with EMC requirements in most major markets.
