Bravo -
There is a company by the name of Speed and Marine, I believe. They make stand alone harnesses like this. I am not sure if they are still making them for the L98 engines but if you google them, you should be able to find out. I do not know if a Camaro harness will work. Good Luck!

I bought a 1988 Corvette motor recently and do not have a wiring harness. I am looking to find out where to get a harness new or used. I was also curious if a camaro harness will work. I am putting it in a 1994 s10 and will appreciate your help.

Yes, this is common and there could be several things going on here, but you will need several different pieces of equipment to test it that is not available anymore. Your best bet is to send it to us (Zip Products) for a rebuild. As of 12/19/2011 the rebuild starts at $389 and goes up to $689 if your C4 Corvette's Instrument Cluster has bad lenses on it.

I am restoring a 1985 Corvette and the insturment cluster will only work sometimes. When it works it does fine and then they will just not work at all can you help me?

Anything can be done, the question is how easily. In order for the fuse box to come out you are going to be moving all of the Wiring Harnesses. The fuse box is where they all come together. It can be done, but it would take a specialty shop that is good with wiring and probably them making a custom harness. I think you would be in the ball park of 6-7 thousand dollars for this to be done right.

I am restoring a 68 and would like to get the fuse panel out from under the dash and moved to the firewall where it is more accessible. I’m getting too old to get upside down many more times! Is there anything that anyone can recommend or do I just have to cope?

Usually P is pink on a Corvette. They also have a two digit if the wire is light green or light blue. This particular wire you are looking at, what does it go to? That could also determine what color it is.

Need the ground connector for the rear tail light harness. There are four, one for each light. I am missing one where can I get one?

In most of the Corvette restoration manuals, the color codes for wiring are indicated by a single letter. I am trying to find out what color “P’ is? Purple or pink? This is on a 1963 Corvette. I have not been able to find a publication where the color is spelled.

@Jeff Trayer I have a C4 Corvette dash wiring harness (instrument panel) for a 1985 Corvette. It has never been used and I have had it since 1985, when I bought the Corvette. It is in perfect condition. Tom Ridgway - Sold the Corvette and wish I had not.

Jim, You should start with looking up the ground locations in a Corvette Assembly Manual, that way you can see where they are supposed to ground. If the wiring harness is bad then we strongly recommend replacing your Corvette's Wiring Harness.

I have a 1979 Corvette, I have some groud wires that are not grounded to any part of the engine compartment and I do not know where they go. I am sure a new Corvette wiring harness would help. What would you suggest?

Ed,
That is a common issue, you will have to have your dash cluster rebuilt. There will also be a core charge included to get new lenses.

I have a 1985 Corvette, the instrument cluster shows yellow squares for mph and the analog graphic is all green. Is this a sun bleach problem? I can barely make out numbers.

Harry,
Yes, the fiber optics are part of the wiring harness and are inside the harness.

Does the 1968 Corvette Headlight & Forward Light Wiring Harness Package include the fiber optics for the front lights? I see that it does for the rear lamps but it's not indicated whether the front has the fiber optics.

Charles,
You have ground wires in the harness that ground your gauges etc. The ground wires bolt to the chassis at several locations behind the dash. It is also important that you have your ground straps that ground the birdcage to the frame and your Corvette’s engine ground strap in place.

I have a 1971 Corvette and have replaced the front wiring harness. I have installed all new components but neither the wiper motor or fuel gauge is working. It seems that something is not grounded properly. Can someone explain to me how the dash is grounded? My Corvette’s dash lights work but nothing on the instrument cluster works.

Dustyn,
As of right now there are no vendors making the engine harness for the 84-96 Corvettes. Used engine harnesses may be available, you shoud be able to find used Corvette Parts vendors in any Corvette related magazine. As far as the weatherstrip, you really do get what you pay for. The GM Corvette weatherstrip was once $600 per door. It has come down since then but it is still expensive. There is cheaper weatherstrip available but it causes other problems such as doors not closing properly, the top not bolting down, and water leaking because it is so hard. The best weatherstrip is the latex brand that is designed just like the original.
