So...do you mean the diagnostics cable?

Yep

Sorry, you need to say what you are after, and what you are trying to achieve.

If you are after full dealer level diags, then £2750 will buy you the equipment, then you need a subscription to webTIS

If you are after cheap and nasty diag system, cheapo tech2, but MUST have proper serial port on laptop. Approx £25

There are a couple of options in between.

Hi TB,

     Got centronics on the brain at present.

              Certainly not dealer levell, or cheapo.
 just need a cable & plug/plugs to connect a laptop with a serial port
for engine & gearbox ecu (or are they the same?)  Just experimental ?
at present

Still not sure what you are after  :-/

Are you trying to make your own diags tester?

If not, what software are you planning on running?

Hi TB

             Sorry about that.  Only needed a quikie. Start again.

got a laptop hanging around only used for GPS.
want to make up a cable to connect to Engine/Gearbox ecu.
That is it for the mo.
So what plugs req
Software now that's another story SH.  

The plug is a standard EODB/OBDII connector, available from many outlets.

If you are writing your own software, then thats fine, but if you want to use prewritten software, you need to buy a lead that is compatible with that software (most leads are unique to the software than runs them).

Does that make sense?

Word of warning - you might need to change the signal levels as well...
