Just installed a Sprint Booster throttle lag reducer on a 2012 JK Rubicon. There's a 50/50 chance of plugging it correctly into the harness; I did it wrong. Reversed the plug and all is well except the Check Engine Light is on. Will the light eventually shut off, will I have to take it to the dealer, or is there a way I can reset it myself? Any help would be greatly appreciated.

 

Pull your battery cable for a minute and kill power. It should reset.

Or autozone can do it with a code reader.
