Post CAT sensor

Final bit of the exhaust turned up today so I refitted it all, the only prob was the post CAT sensor position is slightly different and now doesn't reach the mounting, I presume using a cable tie to anchor it to something convenient will be OK?
This is the 1st time I've worked with sensors and was dreading getting an engine management light come on, but fingers crossed she's up and running with no lights, bloody noisy though without the engine cover.

As long as the cable is well away from the exhaust a cable tie will be fine.
