"How salty" may be different

"How salty" may be different for every palate but some sources indicate that an overnight soak is not too long. (Did you use the preferred pickling/canning salt or table/iodized salt??)

You might keep going with it (if you indeed still have the pickes when you read this). The sugar and vinegar and other ingredients may very well balance the salt and give you the desired result.
