Thread: Tow plugs - how many types are there?

There are normally only two types of round plug a six pin and a seven pin unless this is some kind of specialised one.
The norm these days is seven pin in line as aposed to round.
Steve.

theres 5 (but you'll generally only see #2+3)

1. 5 pin round, 4 spots around a central earth ,rare these days
2. 6 pin round 5 posts around the central earth, common
3. 7 pin round 6 pins round the central earth with the pins spaced around so that there could be another pin at the bottom, common
4. 7 pin round as above but with all the outside pins spaced evenly. only seen a few.
5. the big 7 pin one that trucks use that occasionally makes it onto the landy.

Mine has a 7 pin Large

Mine is "flat", all pins in line. Have to use adaptor ($10 from K-Mart) to connect to other end.

Cheers,
Ruslan

There's more.

5 and 6 pin small round
5 and 7 pin large round
7 and 12 pin flat

Dunno about now but years ago, the type of plug depended on the State in which it was used.

The big round was quite common in some States. I've got a brand new old stock socket in the garage.

See here: http://www.narva.com.au/Trailer_1.html

The new standard is the flat type.
Eastern staters,unsure which ones run a much bigger dia plug than us,its a dead give away to the origins of a vehicle when you see the plug!!!
Was 5 or 6 pin over here,grew to 7,but not as big as dia plug as others use.

Hi catch-22, here’s the pin outs for both the 7 pin Round and Flat trailer connectors.

Cheers.

I assume by the term "clearance lights" - it means side / rear / tail lights.
