Wierd thread subject, but stay with me! 
Will some of the appropriately trimmed CT100 downlead cable fit in the slots of Gulfs' excellent GTI footrest? Maybe hold it in place with some grip-mat, or carpet tape. Then it would look like the raised rubber profiles of the standard loud and quiet pedals! 
i have 400 metres of ct100 on my van, will have a go and see if it fits and report soon as.
Isn't someone on here a $ky installer or sommat? 
Im an engineer not a dish Donkey T_T

Edit: Tried it T_T, and it looks shocking, slots slightly too big for snug fit. and cutting into shape wont cover up ends well. Crap!
