APC Wire Harness

I want to upgrade my headlights but I have not been able to find the APC wire upgrade online. How much does this help compared to normal bulb wattage? What 9004 bulbs work well with the upgraded harness?

is this a relay for your headlights? i recently put in an OSRAM hid kit on my 3rd gen and I love it. The price isn't something most people would want to spend on a hid kit but hey, they look awesome.

apc harness are bacordered until late august. you will not be able to find these anywhere until then, if you are looking for apc specific.

I recently bought a store brand update wire harness exac same as apc wire harness. they are available at www.autodynamic.com
and these give your headlights and hid look (you will be satisfied) for only $30-$40. my harness is on the way.
