Am fitting aftermarket front parking sensors to 06 V8V (LHD), and need to route a wire from the engine bay through the firewall into the cabin. Cursory look under bonnet does not reveal any obvious access holes, but they must be there! I'd rather not drill a new one, so can anyone direct me to an existing point of entry (as it were)?

Tia.

 

If you take off the inner fender you can fish wires into the footwell. I did this with my piggyback ECU for the supercharger application.

 

Thanks. Is one side easier/better than the other?

 

On LHD the drivers side would be better for the PCM is located in the LHF fender, so there wiring and rubber grommets will be there.. unless your talking about a V12V then either side for each front fender has a PCM..I'm not sure on the V8V passenger side if the hole is there on pre V12V model build years..so if you want to play things safe it would be drivers side

 

Thanks.
