i have a set of rc 440's. i was under the impression that rc's were only made obd1.

i have an obd1 harness/injector clips and they wont connect to the injectors due to an extra ridge on the inside of the connector on the injectors.

ive used these before, and could have sworn it was with obd1 clips, but now im guessing that they were obd2?

can i just sand off the extra ridge in there or what? this is the last thing keeping me from starting my car now dammit.

am i just doing something stupid wrong?

 

I'm sure removing that extra little piece isn't going to ruin anything. You have to do it when you run DSM injectors.
