^ shouldnt matter which wire you solder to which lead/ tooth in the connector.... but that resistor will probably carry more heat than the larger ones.... my original design used that resistor type, but when soldering, the connection itself came out of the resistor... two more failed, so i went with a better option and more soldering/ securing to the leads.
.... now.. i would double check the entire set up... make sure your block off plates are on correctly, and that your resistor is still in tact/ operating.
What bike and exhaust you running?
Ultimately i dont think that the block off alone would cause the issues with fueling you describe... i had tried mine before i out the resistor in... and had a CEL, but no trouble running the bike.
Soon after though, i had the bike custom tuned!
have you messed with the throttle control/ position of the cables?
and the throttle bodies... just double check every little thing... it's important to make sure all parts function properly on these machines
Let me know if i can be of more assistance... i hope we can figure this out and fix it easily.
or @JDgun would know much more than I
