Does any one have a color coded wiring schematic for a 1968E 427, B.B. conv./ 4 speed ??

 

the best ones available are from Don Olson:

Each color coded diagram is about 22x34" and includes all electrical options, fuses/circuit breakers (and their ratings), lamp numbers and locations and vacuum lines for the headlamps, heater-a/c, and for the early C3s the windshield wiper door

Don's are the best!

 

I just have to agree

There are several different Corvette schematics available. Compare them and then you can better decide how to proceed.

I have the one from Lectric Limited, the one from Don Olsen, and the one from Dr. Rebuild.
I have to say the one from Dr. Rebuild is the easiest for me to use for my 68 with a May 1968 build date.
The Dr. Rebuild ones not only show the wires and colors but also the correct plugs or ends which makes it easier for me to find the wire under the dash or whatever. I also like seeing the plugs so I can be sure that what is on my car is correct.
I have no business interest in Dr. Rebuild, I just need all the help I can get and his diagram was easiest for me to use
Just my 2 cents

Funny, I have all three of the exact same
The Lectric Limited is good but compared to the Don Olson chart is a childs drawing - it's smaller and therefore harder to read and not color coded although it's still very usuable if you aren't aware of better alternatives.
I also most recently got the Dr. Rebuild wiring charts and there are a lot about them that I really like and I will say that in some areas I do prefer over Don's charts. As you mentioned, seeing the details on the plugs that terminate at the wire ends is very, very helpful and something that Don's chart doesn't illustrate. It does help to identify various correct wires while searching in the car somewhat easier, etc. The Dr. Rebuild charts are broken down to two or three charts for the car rather than just one though - basically a seperate chart for each seperate wiring harness and while it makes each individual harness a bit easier to follow and understand this way is seems to make looking at the entire cars wiring system in an overall view more difficult.
Don's charts show the entire wiring system for the whole car on one large chart so if you need for example to trace a wire from one end of the car to the other end of the car you can do it more easily and it's all in front of you at once rather than having to go from one chart to another.
I kind of look at it as Don's chart as a great overview chart and the Dr. Rebuild charts like a blown-up "macro" view. Because of this I end up using both together. I tend to look and trace issues down to a certain area by using Don's chart than once I've narrowed things down to an area and need/want a more detailed view of things than I switch to the Dr. Rebuild charts for a more detailed view of what's going on and what to better look for on particular wires, connections, plugs, etc.
Using both Don Olson's chart and the Dr. Rebuild charts together is for me at least the perfect solution and I should have mentioned this in my first post. If I was forced to only use one though than I'd still have to choose Don's chart simply because of the better overall view of the entire system at once although if I had to choose just the one rather than being able to use both i'd be most unhappy about it as I really like the overall view and closer macro detailed views I get by using both Don's and Dr. Rebuilds charts together.
