Hi Tonyt37,
I just fitted the N & S wiring to mine and I used one of these - http://cgi.ebay.co.uk/Flasher-Unit-12V-4-Pin-126-Watt-Trailer-Towing_W0QQitemZ130288426393QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item130288426393&_trksid=p3286.c0.m14&_trkparms=72%3A1683%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318
Only £5.65 inc. p&p - Unit looks well made but has a slower flash rate then standard unit, works trailer indicator in dash ok - just remove original relay and plug in.
Hope it helps. TD John

Hi Guys
I fitted the electrics today. Plugged the relay in. Everything worked o.k. Unplugged the trailer board and retested. The trailer sysmbol still flashes. Should the trailer light on the dash flash when the trailer is not attached? Enybody any ideas?
Thanks
Tony

No point in having it if it flashes all the time. It's supposed to flash only when the extra current for the additional bulb is sensed. Could be the wrong value.
Hi Tony37,
Numbers add up like this;
When indicating "solo" - 21w front + 21w rear + 5w side repeater - trailer indicator flashes 'once' when you start indicating and no more.
When indicating "towing" - 21w front + 21w rear + 5w side repeater + 21w on trailer - trailer indicator flashes every 'flash' when you start indicating.
If the trailer indicator flashes all the time when solo check the bulbs in the indicator lamps, if you have a larger load (say a 10w in the side repeater or extra repeaters) then the trailer indicator may flash permanently when solo. Flasher load margin should be around 10W+ extra to operate the trailer indicator.
Flasher Unit is also used for hazard warning - 2 x 21w front + 2 x 21w rear + 2 x 5w side repeaters + 2 x 21w on trailer - total of 126w max flasher load.
If your trailer has more than one indicator per side then add up the total and get a bigger 4 pin unit (e.g. 148w or larger?)
If all of your lamps check out - chances are the flasher unit is over sensitive - could try for a replacement?

it is quite likely the trailer symbol flashes once, it will only continue to flash when the relay senses extra load for trailer board, additional lights etc, it tells you the circuit is good, if you use the hazard fashers the trailer symbol also lights up.
