General Information and FAQ about the design and use of AKM Cables:

• ALL of the AKM cables are for GM OBDI computers from approx. 1986 to 1995. They do NOT work on any true OBDII system, even though some use an OBDII *style* connector. If you've retrofit an OBDI system in to a OBDII car - we're good... if you're working on another style of retrofit (truck, street rod, etc) then we need to make sure that our wires line up. See the "Technical Info".

• RS232 cables are based on the MAX232ECPE (Electro-static-discharge resistant) interface chip, and is fully RS232 compliant.

• USB cables are based on the FTDI FT232BM interface chip.
