I have a 7 pin large round Navra plug, metal, the caravan plug
Looking at the back of the plug (where wires connect) I have pin 1, yellow on top
On which side of pin 1 are pins 2 and 6
Thanks in advance

Look up the Narva website

Narva Trailer Wiring

and select the 7 pin large round.

As per Mal58 then.
Select the 7 pin large round, print it off "in colour" and place in folder. Very handy piece of info for
future ref.
Dave.

Thanks everyone, got my answer.
For orientation purposes, looking at the wire connection end.
6 is to the left of pin 1 and 2 is to the right.

Thanks all

If you are ever looking at the base then the whole lot is reversed except L, R and park.

One way to find out how to wire the plug is to use a meter (or test lamp) and find out what comes out of the vehicle socket. The plug then should have the same rotation. (A word of warning, if you have a Redarc brake controller you can not use a meter. See the user's manual to see how to check the output from the TowPro.)

That only relates to a reading on pin 5 doesn't it? all the other pins will read as normal. How does a meter affect the REDARC unit. Can't see how. Is it a warning about damage to the REDARC or false reading. Please explain for users so they know what is what.

"Is it a warning about damage to the REDARC or false reading?"

Most of the pins can be checked with a voltmeter. Pin 5 (the brake control line) can be checked with a meter when most brake control units are installed but not with the TowPro units.

TowPro brake controllers spend most of their time asleep (just like other models.) Most brake controllers wake up when you press the brake pedal but not the TowPro. You can not detect any significant voltage on the trailer connector brake pin when attempting to test it with a voltmeter. Tow Pros require a solid load on them to wake them up. A stoplight incandescent globe will wake them up.

This appears on page 31 of my EBRH-ACCV3 handbook"
"Immediately After Installation (To be done by a qualified Auto-Electrician)
Test the installation/vehicle wiring. Testing your vehicle wiring is best done by connecting a test light (Max 21W filament globe) to the brake output, pushing the manual override and having someone check that the test lamp lights up."

This is a trap if you have things like hydraulic disk brakes or some models of anti-sway units on the trailer. They do not provide sufficient load on the TowPro output circuit to wake the controller up. Redarc's solution is to wire the same resistor you use with LED turn indicators on trailers (to correct vehicle monitoring circuits operation.) I found this out when I acquired my latest Navara which is fitted with a TowPro brake controller would not operate the van brakes with a Dexter anti-sway fitted. A resistor across the Dexter input fixed the problem.

I see you mentioned pin 2 and 6 for some reason. Doing brakes perhaps? Pins are numbered inside at fixing screws or at pins. 2 is on same side as White wire. Has to be!
1 Is yellow and LHS flasher,
2 is aux power or anything you want to be able to switch remotely. Black
3. Is neg- earth of chassis White
4 Is RHS flasherGreen
5 Electric brake Blue
6 Stop light signal Red
7 Centre, Park lights, side lights Brown

If fiddling with electric brakes and USA origin controller, the Black wire of that is positive. Red is to brake switch and white is to vehicle negative/earth. Just a bit different to AU wiring in places.

If you look carefully at the plastic disc when the plug/socket is apart, you can see the pins are numbered.

At least you can on mine. Cheap knock-offs, maybe not.
