.....
You need either or optionally both, an audible or visual indication that the indicators are operating in sync with your car indicators... I'll advise audible... if the bulb fails on the trailer, it don't beep! .......

That's what I said!   Although I'd suggest using the lamp on the dash rather than the buzzer!

[slightly off-topic ....]  

Having just had the towbar/13 pin electrics fitted, including the "Flash Guard" (?) module as advised by AndyC, all the van electrics now work as advertised BUT the dash tow warning doesn't work - elsewhere is mentioned a relay to go somewhere behind the glove box  and the "Park Pilot" reversing sensors don't shut up when van plugged in...

Any one any ideas on either

Possibly...

The relay behind the glove box is a current sensor designed to display a warning of brake bulb failure on the MID in relation to the trailer brake lights. I assumbe this has been bypassed or the brake lights wired to the rear light clusters so probably not worth worrying about.

The trailer indicator light aparently requires a new indicator flasher module and the light bulb fitting in the in strument panel. You'll possibly need to bypass the indicator relay with audible warning to make it work.

The park pilot requires a connection either side of the trailer hitch fog lamp switch to detect when towing. If you're keen on doing this I'll look up the pin numbers and wire colours involved.

Kevin .. thanks  

The bulb failure/MID thing "appears" to be done by the "flash guard" unit that I bought, as without it I don't get a correct brake light test on start, with it I do. It also seems to monitor the van brake/side lights

The replacement flasher unit/bulb I'll look into.

I would appreciate the info on the "park pilot" when/if you get the chance.

Your help much appreciated

OK. From what I can see pin 9 of the park pilot (violet/white) should go to the feed from the fog lamp switch to the trailer socket. Pin 14 (violet) should go to the feed from the trailer socket to the car's fog lamps (after the switch in the towing hitch socket). I believe the park pilot detects when this switch is open and disables the warning. In addition, the wire link between pins 12 and 26  (grey) appears to be disconnected if a trailer hitch is fitted and connected if not.

All pin numbers refer to the 28 pin connector on the park pilot.

I haven't tried any of this. It's just what I have deduced from the wiring diagrams.

I have aftermarket sensors - I just ignore them

You could always fit a 'Master Switch' to turn them off when towing.
