1 We decided to use the Power Plus 20 Wiring Kit, part number 510008, for Jim's car. There were two reasons we went this route: one is the price. At $299, this wiring kit has a lot of bang for the buck. Two, was we wanted the ability to change the routing of the wiring to hide it all for a cleaner look. The pre-wired fuse box has dedicated circuits for: radio, turn signal, hazard signal, electric fan, brake lights, gauges, headlights, A/C, heater, wipers, parking lights, CB, fuel pump, power seats, power locks, cigarette lighter, power windows, cruise control. The kit features GXL/XLPE (-60 F to 275) heat resistant, GM color-coded, and circuit labeled wire. The kit comes with a great set of color schematics and easy to understand instructions. We also picked up an assortment of the company's brand new wire loom.
