just curious about how many of you guys used a relay with your hid conversion kits on your GS and how many didnt?

and has anyone not used one on their gs and had their stock wiring harness fry?

i have a non-hid gs and i brought the OEM lexus HID and just cut the connector off the 9006 headlight plug and just used the OEM connectors and just plug it up that way... i haven't had any problems

My brother did a retrofit on his ES and used the same wires from the halogen bulbs since the factory fuses were 20A. HID's only require 15A.

Actually the recommended amperage is a 20A fuse.

i don't install any hid kits w/o a relay/fuse for direct power.

I usually recommend it, but Toyota outfits all of their cars with thicker wire gauges than other manufacturers. If you have a relatively new (new as in design type/circuitry, not how long you've owned it) high quality HID ballast (newer= MUCH MUCH more efficient, older/low quality= power HOGS) then you should have no problems running straight off the spliced stock harness. If you are unsure or have power issues (blowing fuses, lights don't always come on, flickering, etc) then I suggest you run a wiring harness. If you have a newer ballast then this should not be a problem.

Personally I have a relay harness running to my HID's...3 sets of relays in fact . I have HID's with boosted ballasts(60W) in the high beam, low beam, and foglights. I kept popping the little automotive blade fuses so I had to upgrade my main power wire going to the headlights. I used an 8 gauge speaker amp wire that splits to the 3 relays and the in-line fuse was replaced with the cylindrical type 60A audio fuse! Firing up 3 sets of boosted HID's at once draws a LOT of current

Now I understand what you were asking. I would recommend running HIDs with relays only. Basically if for nothing else, it is just to do it right. You do it right once, and you will never have to worry about it ever again.

well,, i just ordered a hid kit but it doesn't come with a relay. so where would i be able to get one and how is a relay installed. i heard you could get one from radioshack???

i have no experience with electricals... any help/diagrams and suggestions to where i can get the part would be greatly appreciated.

slick and cliffud, thanks for both of your help via pm thus far!

You can pick up relays at Strauss, Autozone, pretty much any decent auto shop. I am not that great with electronics either, so I don't want to put you in the wrong direction. I don't know the numbers that they follow either, but you basically need one that will close a + circuit once the lights are turned on. That +circuit will be the new, thick wire that will actually power up your lights. I am guessing it will run straight from the battery. Can someone else chime in here.

I'm interested in the same info.. also what's a good hid kit? everyone says the housing is very different for the hid vs the nonhid.. will I be blinding people? interested in knowing.. also I wanted to make my daylights to be bluish like hid anyway to do this? thanks guys

i would use a relay... doesn't really hurt to use one. better to do it right the first time.

Hope this helps. I'm running this relay currently on my aftermarkey HID on my 97 ES. No problems.

what kind of relay is that?

thanks for the diagram bunthy. i will use that as my guide once i get my relay.

its generally a standard automotive relay for use with any high wattage bulbs while still protecting the OEM wires and circutry. In this case it has additional fuses for protecting the ballast.

The same one but without the 15amp fuses for my 100wt fogs lights.
