Hi Paul , If you don't get sorted on here, Which i'm sure you will , as this site never ceases to amaze with all the knowledge and friendly, helpful folk. Give George Pinder a ring at Tytherleigh Vehicle Electrics , based at Chard in Somerset . I am happy to come along with you if it helps , as i took my Elise there last year. Not sure how far this is from you in North Dorset . Good luck .
