I would probably modify a painless wiring harness./the original harness is not equiped to run guages.The correct harness is available from MG Magic but it is a little pricey.Somewhere around $500.Then again,a couple hundred for a harness to modify,a bunch of work,it might not seem so high when you can just match the codes on the wires to the manuel.I just redid an old one and all the code tags were still on the wires.I just put it together according to the book.Nothing to it.You just have to be able to read and count to ten.August 8, 2007 at 10:27 pm #237083Paul MossbergKeymaster
If you want a copy of Classic Roadsters’ schematics, let me know. I have my complete assembly manual.
An alternative somewhere between MGMagic’s “complete” and starting from scratch…search for Dune Buggy wiring harnesses. They will have most of what you need.
Here is one example, http://www2.cip1.com/ProductDetails.asp?ProductCode=ACC-C10- 5720. This harness includes color coded looms with fuse box and connectors, allows for headlights, tail lights, turn signals, dimmer switch, license plate light, gas gauge, speedometer, windshield wiper, starter switch, horn and voltage regulator. It’s less than $55. You would have to fabricate wiring for other gauges and lights for them. There’s a link to the wiring diagram for this harness on the above page so you can see what you are buying.
Godo old JC Whitney has one too, for about the same price http://www.jcwhitney.com/webapp/wcs/stores/servlet/Product?s toreId=10101&Pr=p_Product.CATENTRY_ID%3A2001329&prod uctId=2001329&catalogId=10101
Like many of the things we do…your choice is between $$ and time.
Lemme know about the CR diagrams.

And,I have copies of the FibreFab VW wiring harness although I doubt there is any real difference from it and the Classic Roadster Paul is talking about.One thing to add about any other than the correct harness for your car is that you have to run ground wires for everything.They all rely on the steel body to ground the components.August 9, 2007 at 12:09 pm #237085Paul WeatherholtParticipant
Keith and Paul,
Once again your guys a troopers thanks for the info…Sounds like it should do it the book way which I also have a copy of..Thanks.August 14, 2007 at 11:29 am #237086Mark HendricksonParticipant
Save yourself the headache of trying to wire it up like the manuals tell you. Spend a little bit more up front and get a wiring harness kit from Painless, American Auto Wire, Ron Francis Wire Works, Centech, etc.
A 12 circuit basic Hot Rod kit will do. Call these people and tell them what you are doing. They are all very helpful.
These kits are VERY SIMPLE and complete. They will have everything required to do a premier job. Again, the companies are all helpful.
In the end, you’ll probably spend less than a do-it-yourself job following the manuals wiring schematics and end up with a great job.
DON’T BUY CHEAP…GET A GOOD HARNESS!!!
