i was wondering what car i need to get a resistor box that will plug into my factory harness without cutting the plug off and soldering the wires together. i have a 94 hatch with a gsr. and the stock cx hatch wiring harness

 

im think you can use one off any honda, not sure of obd compatability issues, if they're even are any. As for plug n' play with your car, you can forget that. Theres a few write-ups of how to install one. Do a searh though, if you havnt already.
