I emailed hidexpert and they don't come with a new wiring harness...they may still be plug and play but with stock wiring harness.

 

but wouldn't that be the point of a plug and play system. Something that plugs into your stock headlight harness to power up the HID ballast or am I way off base on that?

 

I think most kits plug right into your OEM light harness but some better kits come with a harness with upgraded fuses and relays to ensure you do not draw a higher current from your stock harness than it was designed to provide. I emailed hidexpert.com and they said it's plug and play but it doesn't come with a new harness with upgraded fuses and relays.

 

all bulbs that are 9006 all have the same plug that is why it is plug and play! you could always splic in a fuse on the power side would take you about 10min

 

ok also couldn't you jump up the ampage of the stock fuse in the fuse box?

 

9006 bulbs are 55W and most HIDs are 35W.

Even the new ones a only 50W. I've never heard of anyone changing their stock wiring and harness when using a good HID kit.

I guess you could play it reaaally safe

 

I am looking at getting the D4s kit for my main beams, I like this set up as it has proper ballasts and phillips bulbs on the hid dips it has a 20A fuse so i think i will make up a seperate harness with a relay to protect my wiring etc, as on the mains it only has a 10A fuse.. on the start up with hid it will draw more than 10A so it's good practise i think to do this, the light output should be amazing

has anyone tried the hid on the mains? I wouldn't flash my mains during the day with this set up, I thought maybe to have my foglight swicthed to the on position then just flick my sidelights on to do this? I have the HIR bulbs in my mains now but have to say they are bright but not much brighter than the PIAA factory upgrade that came with the car..
