Great Day....I know this topic is a popular one...but I need some advice...just received my new glass lens replacement housings, which came with a complete wiring harness....switch, relay..etc.  If I am going to be swapping out the OEM assemblies with these, which are H11, will I need to use the harness to give the lights enough power?  or can I simply splice in the H11 connector into the existing light feed wire?  I really want to do this right, without "hacking" it up...Thanks!!!!!!!!!!!
