Thanks!

Lucas is making some very nice repos. Just go to their website and search for the bike you are building. Lloyd L

not sure what harness you are looking at .
could be for an older model year harness
where the lighing switches take bare wire ends
into screw terminals ?

THANK YOU BEACH; I DID NOT TAKE THAT INTO CONSIDERATION. THEY DO LOOK WELL MADE. I WOULD US ONE UNLESS I COULD FIND AN UNMOLESTED NOS ONE AT A REASONABLE PRICE.

That's true but only if you already have crimping tool, wire strippers, a basic selection of wire and bullets etc. I re-wired my T100R from scratch and had absolutely nothing to start with. By the time I'd bought everything I needed I'd spent about £170, the cost of a decent aftermarket harness. Having said that I'd do the same again, being able to make improvements and being sure that it's all put together correctly is well worth the cost and effort. Plus I now have a good selection of electrical tools & consumables should I need to change or repair anything.

When it comes down to wiring harness, all will require some additional work (soldering, crimping, etc)

Parts get changed or added (like Boyer's, regulators. etc)

The new Lucas harness are spot on, however you might have to do some work

Last NOS harness I purchased needed some extra wires and connectors

Just the nature of the hobby

It’s each to their own, I’ve made a lot of harness and one of my
Biggest regrets is loosing the proper and expensive tool for crimping Lucas bullets. There are also some
Connections which are impossible to obtain although those
Making looms Professionally are able to source them.

The first loom I made I bought in full rolls Key colours, red, black, brown, brown and green, white. And then large amounts
of other colours.

The last loom I built was for my oif, I bought extra wires in for that as well as some
Boots to cover the cables under the tank where the switch gear comes together.

Everything gets wired to where it should be (in theory) so there isn’t any extra wires running anywhere. I say in theory. After the first loom I made for my A65 I made another loom as I added some
Additions like an ignition light and a engine kill wire for the ignition back to the electronics. Thought that would have me sorted.... there have been other additions to the loom since as well.

About the only thing I don’t do on my own bikes is the chrome and wheel building. All the paint and mechanics is done by myself, it’s
nice to be able to look at something and not only Say I have done that... but to also have a better idea what might have gone wrong when or if it does.

All good information, thank you!

I find wiring quite irritating, thus will buy my new harness rather than attempting to make one. Like they say, work to your strengths!

The British Wiring site lists a harness for my 1970 A65, but the note says it includes "indicators"- To what are they referring?

I doubt they used that 70 loom in 71,they changed the frame at that time so it wouldn't be any good.

Just like my Lucas 1969-1970 A50 / A65 harness on my site, they have the wires in place to run indicators

Did they come that way from the factory? NO

Does it make a difference? no..

Just bypass the wires used for indicators

The 69~70 harness has indicator wire features
not exploited until the 71 harness ... the Brits were under some deadline to put turn signals on bikes exported to the US .
the wires started showing up on harnesses before bikes started showing up with turn signals .
or the wires starting up on the wiring diagrams any way .

The new 71 harness was for a new frame with new handlebar switchgear and shared with Triumph .

Lucas Repo 69~70 harnesses have the indicator wires .

excellent info

i have a 69 A65 that suffered under a dpo who didnt like the Lucas crimps, so he cut them all off and substituted bayonets.

as a rezult every wire on the bike is an inch too short. maddening.

no turn signals but this info that the harnesses had the wires will help me buy a replacement that will work.

im going back to stock electrics on it. no EI, electrinic regulator and so on. wel ll see if im any better able to keep it running than i was back in the day


every day you do not take a chance is a day of your life that you will never get back.

I always find that making your own harness forces you to understand how the bloody thing works.

It also makes diagnostics easier if you have problems. You tend to remember stuff you built from scratch.

You do need the gear though. Probably not economic for one bike.

I’m still not a robot.

Great thanks. I assumed they meant turn signals, but had never seen a '70 or earlier so equipped.

It depends if you are making a bike to impress others or for your own riding pleasure
If the latter then all you need is an uninsulated termina cripming tool, some heat shrink & a hair dryer.
Then if you want to go really pretty a roll of self amagamating loom tape and an assortment of blade terminals & plugs for them
