1991 GMC Suburban Harnesses at Tuners Depot
These Nokya Heavy Duty Headlight High/Low Beam H4 Wire Harnesses have been designed to be plugged into your GMC Suburban's stock wiring. Aftermarket bulbs or not, your GMC Suburban stock lighting H4 harnesses are not designed to handle extended periods of use, or operation in adverse or severe conditions. To address this, Nokya offers these H4 Heavy Duty Headlight High/Low Beam harnesses as a cheap and relatively easy upgrade to your stock GMC Suburban electrical system. They work as replacements for damaged stock H4 harness plugs, or as complete upgrades as a precautionary measure against harness plug burnouts (which can permanently damage your GMC Suburban headlight housings). These GMC Suburban Heavy Duty Headlight High/Low Beam H4 Wire Harnesses also help to handle the increased demands of aftermarket Headlight High/Low Beam bulbs, Nokya brand or otherwise. Each set consists of 2 harnesses.
