Default RHD Wiring Harness

What are you 'export guys' using for wiring harnesses for a 1930?

I just use a LHD harness and extend the required wires. It is the light and horn harness that is different, the engine harness is the same.

Thanks. Is that the best option, -or just what restorers are using? I hate to extend wires as that won't look the best since the power wire from the generator would need to be lengthened and would easily be seen.

Effectively the LHD loom is turned upside down to connect to the headlights . The power wire to the light switch is joined under the rad where the loom runs across same for the horn wires . I use the same pattern wire so it looks original and as the connections are under the radiator they cannot be seen . I make sure that the connections are watertight as that area can get wet etc etc .

Tell Tyree Harris what you want and I bet he will make one up for you as specified.

As others have said, the only option is to use a LHD loom, flip it over and extend the short wires and add wires for turn indicators if you are fitting them. Indicators are dead simple to install here as the brake lights have nothing to do with them.

I have purchased both my RHD harnesses from a local supplier, unfortunately he has now passed on, so I am unsure what the other local suppliers are offering. In the U.S. Rhode Island Wiring offer a RHD harness. (http://www.riwire.com) I have no experience with their products, but looks like a good alternative to splicing wires on a LHD loom.

Bick's suggestion of Rhode Island Wire is good. I used them on an antique tractor restoration. They have every cloth color combo under the sun and a loom to wrap them per your instructions.
