I need the dianostics plug you use to retreive error codes from the computer. In the manual it is shown as part of the dash wiring harness.

From the dealer, you can only get the plug WITH the dash harness for something like $450.00.

I ONLY need the plug.

I don't think it makes a difference; but it is for a 2004 S2000 motor which is in an Ultralite Lotus 7 Clone.

If anyone can point me in the right direction I'd really appreciate it.

 

all the plugs are ODB2 , you can just cut one off from a junk yard from any car that has it. Just make sure your color match up is correct.
