Hey All:
I am needing wiring information for a 1999 Lexus IS 200. Its pretty much the same as the IS 300, different motor/transmission but other than that, identical.
I could work off of the IS300 diagram, however, having never done a IS200 before I want to make sure everything is up to par before I start substituting one diagram for another.
Thanks in advance!

Amazing! Thank you so much!
I'll have to find the Neutral (+)or(-) on my own. Should be the same as the IS300 . . . which I've got notated somewhere in my box.
Thanks again!

DEI European info would be based on the UK spec which of course would be right hand drive.
The door locks alone are a PITA. Buried under a kick panel fuse box is an ivory/whitish box held on by 4 x 8mm spanner size castellated nuts.
Undo them and unplug the box. Open it and look at the circuit board.
At one end are the two thickest tracks.
Cut both with something like a Dremel tool, make a 3/8 hole in the cover opposite and resolder each track to a 4" (10cm) length of cable. Bring those cables out and reassemble and remount the box.
Now cut those cable and test using key in door or OEM remote to find the lock and unlock motor wires and wire as a 5 wire.
Still interested? Then one of those plugs you put back has all the door and trunk and if I remember hood triggers! But then if the dome light shuts down when the vehicle is locked we know the answer there.
My question...wth does the poster mean by "neutral (+) or (-)?
This isn't an electric vehicle powered by a wall outlet you know.
The light colours are actually the L/R indicator colours but we use them anyway.
Ignition loom and the tach, pin 9 by the way are the same as Metz listed.
There will certainly be an immobiliser to by-pass, 55UW not 555F is the way to go, also keysense definitely needed BLACK / YELLOW at the ignition switch. All in all one of the most fiddly cars I've ever worked on, at least all the trims go back nicely.
Mind you for fiddly you can't beat chucking a Bluetooth kit into the latest IS and having to run the lead to the amp at the back.

P.S. WTH would someone want to import a 2litre Japanese vehicle from Germany when you could buy a 3 litre version in the US for less money.
Unless US forces. I've done a Japanese GS 300 twin turbo at a USAF base here, it's the hummer with the roof mounted Ma deuce pointed at you as you enter the base which rather puts me off.
The PX reinforced everything I like about the US, especially the prices.

Hey -
Its a stick, but the customer wants the remote start to perform as if it were on an auto (e.g., not having to turn the car off with the remote) when the car is in neutral. Therefore, I need to find the wire telling the BCM (yes I know GM terminology, but it works) that the car is in neutral. That way I can connect the Remote start ground wire safety function that everyone always ties into the main ground on the alarm or just chassis grounds it, to either the "neutral" wire if it is (-) when in neutral, or hook it up to a relay if it is (+). I hope it is (-), else the customer will have to jump the car is left sitting for 3 weeks or so. I don't think Toyota/Lexus was doing data at this point in time for neutral.
And yeah, I asked the customer myself, and he quickly educated me that you can pick up a IS 200 in Europe for approximately 2300 Euros, which is what he paid for his. Add shipping and the exchange rate, and hes driving around is an IS for ~ $4500, still cheaper than the beat-to-hell bottom of the barrel IS-300 here in the states one can pickup for around $6500. Additionally, it has better gas mileage than an IS300 and it works off regular.
I took the car around the parking lot, it feels very similar to the E46 323i. Not a bad car for $3k.

Additionally, I see you are from the UK. You can get a decent IS200 with low mileage for less than 2000L. Not a bad deal if someone needs a cheap beater with the ride of a semi-luxury car.
