Help please- making the cables iva friendly

How would you guys recommend attaching all your cables to the chassis? Also what protection will they need?

Cover the cables in convoluted sheathing and p-clip to chassis, or use cable ties with saddles.
This will get you brownie points at IVA, and is a safe way of doing it.

Something like this. But rivet or screw type, not self adhesive.

I have my cables in split tube, wrapped in pvc tape. Attached to the chassis by cable tie saddle blocks riveted to the chassis.

I can only tell you what I did and I have not submitted it yet to IVA (Next month I hope). I put all the wires in a loom and used self adhesive black nylon loom tape over the hole length. In the areas that are not exposed to the wheels or chassis edges I used rubber sleved metal P clips at suitable centres. On exposed areas like wheel arches or chassis corners I used split plastic conduit to reinforce the loom. On areas where it had to follow the countours of the GRP panels I used heat resistant sleeving covered intermittantly with a bit of GRP tape and resin. Where I used plastic P clips I used some clear plastic pipe to add abrasion resistance to the loom. If you are going down that route remember to test your loom before the loom tape stage even if it is with a multimeter. Best of luck, I found the wiring a chore.

You know what? I think you may just about scrape through IVA doing that.

Secure the loom every 200mm to your frame.

cheers guys- luckily the wiring is all finished and tested, your advise is greatly appreciated- saddle back cable ties and conduit here we go!

Mine using flexi tube, plastic p clips and rivnuts.

Loggboy... Not sure how relevant this will be given the low mileage of the car but I have been having issues recently on a 10 year old polo where some of the loom is not wrapped with tape where it exits the convoluted tubing.... The vibration has caused the insulation to be compromised and in some cases the cables have failed completely.

Dont need to wrap the entire loom before putting it into convoluted tubing but I would seriously consider using self amalg tape on the wires a few inches back into the tubing

Appologiese if you already intended to do so

Whatever you use, DO NOT use self-adhesive cable tie pads, mine failed on a few points first time and that was one of them. He argued that they 'could' come away after time and in the heat, fair point I guess?

Just my 2p worth
