Is it generally acceptable to secure covered/protected wiring direct to appropriate chassis rails with cable ties or do you have to use bases/p-clips?
Can anyone point me in the direction of the current (SVA) requirements for forward vision please?
Thanks

Just think about protecting the wiring when you do your fixings - that's all the inspectors are looking for.

My wiring loom is covered in spiral wrap, so I can fix it almost anyway I like. It's tie-wrapped to the chassis in some places, to pads in others, and P-clips elsewhere. If the wires were loose then almost any fastening could be criticised.

Mind you - if I was doing it again I'd use split convoluted tubing rather than spiral wrap, which is a total PITA when you want to change something!

If you use tie-wrap sticky pads, remember to use some form of mechanical fixing as well - a rivet through the middle, or similar. They won't accept the sticky pad on its own (which is fair, as I've had one or two come adrift without help).

Pretty much most of mine is in convoluted tubing apart from the very ends which are proper harness tape. It was more a case of, if I have a length of convoluted tubing taking the same route as a chassis member, can it just be cable tied to that rail?

Don't see why not - if it's safe, not flapping about and not likely to contact anything it shouldn't (e.g. exhaust, fuel or brake lines).

Yes as long as its secure. Maximum spacing of 300mm between fixings.
