If you are looking for the earth connection to brake the motor I would expect it to be just a link on the relay base. Just swap the relays around as most of them don't use the normally closed contact anyway - if the problem goes away then you know what the cause was.

Iirc it is on the fuse box can't remember which one it is though....

The motor drive relays that provide a brake when the limit switch opens (R5 & R6 on an SS1) are mounted on the armature beside the motors - so I presume there's only one on a monobody (SST/Sabre) and it's either going to be by the motor or possibly on the inner wing. It's definitely not in the fuse/relay box.

As Phil W says at the start of his excellent guide,

Two methods can be adopted to find the root cause of any problems:

• Guesswork and replacement of components until the problem is discovered
• Using a logical method to trace any faults by means of elimination

There are some photos and discussion about the SST/Sabre headlamp motor in my project thread here http://www.scimitarweb.co.uk/sgwrs/viewtopic.php?f=20&t=10566&start=1050, which may help.

when I switch off the headlamps they continue to cycle up and down a few times before staying down.
Is there a simple cure or is this going to be difficult?
Any info. much appreciated, thank you.

It can really only be either the limit switches in the lift motor sticking or more likely to be a sticky lift motor relay, which is located near the motor itself. and prone to weather ingress over time. Referring to the circuit diagram, you're looking at M6 or R5... the SST doesn't have M7 or R6. Just swap out the relay, it's a standard fit and should cure your problem.

The only other thing it might be is pull-to-flash contacts too close to each other on the column stalk switch... had that on mine once... if you so much as looked at the dip lever stalk the headlamps popped up and back down. Just increase the gap to eradicate accidental triggering.
