after arriving at destination the trailer plug was stuffed...Again! had come out!
the last two times this had happened i reckoned that we had not put the male plug in correctly and or not made sure it was not locked in?

cant be me...must be something else?

look for common denominator...lots of kilometres on dirt roads...must be rocks flicking up from under car and catching the tangs on part of plug that locks over male (trailer) plug....

any one else had same problem
its a 7 pin (round type) Brylite female section plug mounted to right of hitch on genuine toyota tow bar on 100 series.

G'day Nudenut,
A mate and I both tow trailers, his had the same connection as yours and the same re-occuring problem. We changed it to the square type .... no more problem.

Yep I agree, change to the 7 pin flat, at least it locks in tight.

G'day Nudie,
I use a NARVA 12 pin flat. It has the standard 7 pins on the top row and 5 larger, heavy duty pins below. These later ones are for charging battery, running 3 way fridge in the camper etc. The camper has the matching 12pin plug and my tandem 8' x 5' box trailer has a standard 7 pin flat plug, that can still plug into the 12pin socket. I've been all over the bloody place and have NEVER had a plug come loose. The 12 pin unit can take the place of an Anderson Plug if you use one too.

I have changed over everything to the flat plugs mainly because they are more compact and tuck up better out the way. You can buy a genuine Toyota plug for the 100 series which plugs into the exidsting loom part no. is PZQ6160010

Mine popped out once or twice on a trip too - I just put a medium zip tie around it the union....worked fine....zips can be snipped off and replaced each use en-route. Didn't waste many (bought in bulk) - might go the square plug with the new camper eventually by design as suggested above are the best !
PS: Just remembered....a small stone guard behind the plate that holds the female trailer plug is a must in my view.

I use a Britax 12-pin flat plug for my dirt road caravan. Same as the 7-pin but with 5 additional pins underneath the 7. The additional 5 pins are rated for 30 A as opposed to the normal and smaller pins that are rated for 20A.
I use the lower pins for power to my van mounted 3-way fridge (while travelling) and to the house battery.
Spring loaded trailer receptacle holds the trailer plug in place. No problems so far.

I have had the flat one pull out also, I just wrap a bit of insulation tape around the lot.
