Description The single most cost effective upgrade one can do to the headlights on a 80 Series is to install a upgraded wiring harness. Low voltage due to losses in the stock wiring can reduce the light output of the headlight bulbs. In addition, if higher wattage headlights bulbs are installed, the oem harness and plugs can melt due to excessive current draw. Improving the current delivery to the headlight bulbs are achieved by using this plug-in harness. The concept is that power is drawn directly from the battery using wiring that is thicker than stock, and then delivering that to the headlight bulbs in a short as possible way. Switching is achieved by two heavy duty 30 amp relays and the switching current is supplied by the existing headlight connectors. The harness installs in 30 minutes.
