Hi all, finally getting a chance to look at the issue.
Removed bumper for easier access to wires and everything seems fine so far. Did a continuity check on the 7 pin electrics and found the issue I think.
In Toyotas instructions (PZ457-J9564-00) the pin layout on page 7/14 is:
1
2 6
7
3 5
4
However, on the car, the cover to the 7 pin connecter is reversed a little (its not upside down), so:
1
6 2
7
5 3
4
When checking the continuity, it's wire as the plug cap states, NOT how Toyotas instructions state pin their instructions.
SO... I think that when the car lights are turned on it sends a signal as though I'm pressing the brakes which will stop cruise control working.
