I am in the process of installing aftermarket driving lights on my 00 Accord. I want them to come on when I turn on the high beams. I normally use the high beam power wire on the headlight but I have a Canadian car with daytime running lights and a constant 5v to the high beams when driving. I need to find a trigger wire from the switch. Can anyone help with this ??

Also I am looking for a wayto run wires through the firewall but cannot find any easy way without drilling a hole - any ideas ??

Thanks in advance.
