I have just fitted cruise control to my sons octavia vrs. Brought from dealer £63 all in. fitted the switch ok. A little problem with the wiring going down the left hand side of the column, soon sorted out by refitting the wiring loom down the right side. Ran the wire to the fuse box o/k, and to the ecu. Thats when we hit a problem. could hardly see the pin numbers( well am getting old lol) pushing the terminal into the ecu plug was a big problem,would go in so far and stop, Could see the wire had not gone all the way in,So pulled back out. After several times of doing this the terminal broke.(a few choice words were said).My son posted on here and and a very kind skoda member sent us some terminals and a couple already fitted to wires. He also sent my son an e-mail of how to dismantle the ecu plug. What we found when we stripped the plug was that there was terminals aready fitted to the plug!!! no wonder they wouldnt push in and broke. Nothing in the fitting instructions about it at all. After stripping the plug and terminals pushed home no problem.Re-built plug. put on my mates vagcom, job done and working no problem. anybody fitting one make!!!! life easy ( strip the ecu plug down) lol

Funny you should post this, as i had similar problems. Firstly the numbers on the ecu are so dam small you can hardly read them (only list then in 12 places going up in increments of 9. Then as you state you have to remove the blank pins prior to fitting the new connector pins from new loom into the slots. Also before you do all that you have to pull out the purple plastic tab so to allow the old pins to be removed and new pins to slot in ok(the purple plastic tab acts as an additional securing device to the pins)

I took lots of pics so will post up a DIY when i get chance
