I got the female connectors from other VW's in a scrap yard.
Its been a while, but iirc I only needed 4 resistors, x3 were the same, I sourced them from 9N polo's - on the front of the gearbox, only one per car so I had to harvest several cars chopping a good bit of loom attached. Think the last one is the connector to the SAI pump, easier to find.
I opted to retain the 'front panel and engine cover, looks neater and if I need access its only a couple of clips & 2 bolts
Whereabouts are you in Scotland?
