dark 138, i dont know if it is the cause of fuse blowing....but mine is hooked up together...... like joined the two cables together onto one and then ran the single to my ciggarett lighter....(hardwired it to the ciggarett lighter) and it blew my fuse twice.....last time i had the neons in my other car...my friend did it for me and he connected the neons to another power source.....dont know how or what!!...so trying to find another one in the jazz..if anyone know where i can hardwire the neons...it would be great!!..thanks!
