Hey guys, I recently purchased an hid kit for my celica and it looks amazing, but i want to swap out the fogs and highs too. Can I do this and it not effect my car? and is it necessary to have a relay harness attached to all of them? - Thanks

yes.

You can do it, but it is illegal in some places and every other driver on the road will hate you.

daftboy did this, he didn't have any probs AFIK, I think he relayed them all.

you can swap out the fogs and won't run into any problems, most HID kits are plug and play

however, i don't recommend you doing the highs. HID blubs lose life if they are switched on and off frequently or if they experience frequent changes in power to them (ie. when you are flashing your high beams)
