Have 98 RX7 and trying to get Headlight harness apart under dash. Have disconnected cluster and seperated harness from light switch but It looks like harness under dash is piggybacked with another harness with a piece of black plastic slid between the two LARGE harness. Cant figure out how to remove them. It seems like the two large harness are slid on this black plastic

 

a good eye,an exacto knife and precision?.(the reply bumps your thread anways!)

 

Thanks but I could use a little direction.
