Feel free to move this to a support forum, my "customer" status has not yet been applied.
I installed the CC today, and seem to have run into a bit of a snag.
For whatever reason, I can't seem to get the cruise to engage.

I've thrice checked the wiring, and am confident that the correct wires are in the right place in the ECU as well as in the provided red terminator. The wiring from the stalk to the A451 unit appears to be fine, as I was receiving a stuck button rapid flash until I backed the replacement cylinder off a bit.
Essentially, when I press the button to engage the cruise, the LED does not light, and the car does not maintain speed.

Any pointers would be appreciated.
Thanks.
