To replace OEM plug

Please note, this product is whats needed to REPLACE the OEM plug in a 1997 Chevy Silverado. This is NOT whats needed to connect an aftermarket head unit to the OEM harness. Sonic's recommendation got this one wrong, big time. My reviews on this product are based on what its proper use is.
