Just bought the charging plug from Andover that will fit into existing plug on my MK 3

My question is has any one experience or tips on wiring the dual male plug lead that plugs into the bike mounted terminals
The outside plug has one inlet for one wire that somehow needs to seperate for the positive and negative leads
The 2 male leads will unscrew from the casing but still not clear on best way to secure the wiring
Also there is no marking for the + or - leads so is there any tips on making sure you will connect these correctly once wiring is done

You can wire it how you want as long as both pieces are the same. However, the size difference of the pins is not obvious and it's possible to try to plug it in backwards which could be bad to very bad depending on which type of device you try yo connect.
 
Is the plug just meant to be a protective cover to the female outlet side? Do the male pins fit in the socket side in either orientation or are they different diameters?
Bit sketchy if either orientation is possible!
 
Also, I beleive original intent is as a power take off, to power your shaver etc. Not as a battery charging port since this would mean hot exposed male terminals on plug side. Never a good idea.

No (see below).

They are different diameters but it is still possible to touch the pins to the wrong sockets.

From the Riders Manual:
charging plug wiring
 
Thanks for the replies
I was hoping to use it as convenient charger plug but looks like it is not that practical
Oh well maybe I will get an electric razor for Christmas
FYI the leads are same size and not that snug of a fit
 
I have used the socket to charge the battery for years without any problem. I use a shortish twin core cable with Tamiya type connector at the other end, as used on a lot of modern battery chargers. Doing that you can connect the short lead before the charger so polarity is correct. You could use a small blob of paint on socket and plug if you are worried about getting it the wrong way round. As stated previously, it won't fit the wrong way but you can touch the terminals and get power out in reverse polarity briefly.
 
I use a standard SAE type connector attached to battery terminals via crimped on ring fittings. This connects up to SAE connector of my Battery Tender device for maintenance charging. Can also use that same connector to run accessories like heated vest etc. Only issue on positive earth bike, the exposed pin on the SAE is negative so gotta be careful not to let it touch any earthed metal. I keep it capped off when not in use, tucks away easily into battery compartment.
 
I have a 5 amp fuse and a pair of alligator clips that I can plug into my aux socket. As mentioned, the plug only goes one way but you can make contact with the pins without pushing the plug home, so it's best you leave the load disconnected until after you get the orientation right.

I bought the plug/socket from a Brit parts supplier and found that the plug didn't fit my original socket so I had to mount the mating socket too. The biggest issue I had was that the plug wouldn't accept anything bigger than a 22 ga. solid wire. PMRO.
 
I did mean pins
Apologies for the rhetorical error
On re inspection I did notice the different pin length
I am a stickler for original look but appreciate the tips
Should find a way to make it work
 
The pin diameter is different not the length, at least on the originals. You can use it to charge the battery but as mentioned you can touch it backwards and make big sparks! I used one wire from the hot pin to the negative charger lead and connected the positive charger lead to the z-plate.
I now use the official Battery Tender pigtail that comes with it which has a 3 or maybe 5 amp fuse. No good for heated gear. If you have positive ground and use an SAE connector you should have a fuse of some sort in the pigtail because of the hot exposed pin. And keep it capped when not in use.

I made this rig to charge my battery Thru the power “outlet”. The

are clearly marked to avoid confusion on hook up to any charger with clamps.

In search of originality, I installed the plug and socket on my bike. I have used it to charge my battery and it works fine. True, the pins of the plug could touch the socket with the wrong polarity. But the difference in pin size is pretty obvious. And a small dob of red paint on the socket and the pin should rule out operator error.

What did you use for the connector block and the pins?
 
This pigtail has been working ok for 15 years now. It primarily gets used to power a heated vest but also works for battery charging.
