You can get the skinny injectors with EV1 plugs. So you'll need to look at the connector more so than the injector body to determine which one you're wired for. If it's the stock 95 computer and harness, it should be EV1. No way to tell from the pic if they mixed & matched computers or harnesses between the '01 and '95.
One thing's for sure, if they're skinny injectors, they aren't the stock '95 19lb injectors. So you'll probably also want to pull one out, get a part number, and determine what you're actually running. They might already be upgraded. You might also already be tuned for them or have a matched MAF.
My advice, if it's running fine as it is and you're not planning to upgrade any other hardware, there's no reason to think about changing them.
