Thread match to electric lead (5)

I believe the answer is:

twine

I'm a little stuck... Click here to teach me more about this clue!

'thread' is the definition.
(I've seen this in another clue)

'match to electric lead' is the wordplay.
'match' becomes 'twin' (twinning is a kind of matching).
'to electric lead' becomes 'e' (I can't explain this - if you can you should believe this answer much more).
'twin'+'e'='TWINE'

Can you help me to learn more?

(Other definitions for twine that I've seen before include "Garden string" , "Curl; string" , "Tough string" , "weaving" , "wind" .)

I've seen this clue in the Sydney Morning Herald.
