I replaced my brake caliper on my 1989 honda crx si type r. I did it on the passenger side. Put everything back together and took it out for a quick run. My C.E.L came on after half way down the street. How do I trip a code on my ecu since I can not find my OBD connector?

 

Did you mean to check the code? These cars used an older computer style referred to as OBD0. They do not have a service connector. Lift up the passenger carpet and turn the ignition to the II (ON) position and it'll blink some codes at you.
