CAUTION: Book, Manuals, CD's, DVD, Guides and Posters are not returnable.

oOSOEZ Wiring Guides were developed circuit testing actual Corvette wiring harnesses. These are not reprinted colored in GM or AIM schematics that are notorious for omissions as well as numerous errors.

Easily ID wire Circuits, Junctions, Splices, Connectors, Routing, Entry, Gauges, Colors and Locations plus related Miniature Bulb and Fuse Sizes. Did you ever look at a Fuse Box and be able to read the writing?

Laminated 12x18 in 14 mil clear plastic these will not easily stain and they lay flat and don't roll up. That's important. Those large thin plastic coated ones roll up like a window shade. You need 2 hands or masking tape or a helper. Plus they are so large, you could never look at them while under the dash or the hood.

Circuit Tested: An accurate in an intuitive easy to understand format. There is no special electrical skill or magnifying glass needed to understand these and identify many electrical problems.

FACT: All previous schematic are loaded with serious errors and omissions copied over and over again from GM workshop manual, to Assembly Instruction Manual to Service Manuals to Chilton, to all the rip offs sold on ebait. To even the crappy compilation of electrical schematic for numerous years offered as an NCRS published book. You would think their advertisements would be truthful and accurately forewarn: its just really a copy of inaccurate incomplete information. One of their guru's told me - although inaccurate - they have Historical Value!
