AT200/ST204 to ST205 Combo Meter How-To Options

[WannabeGT4]

1. You will not have a cruise control indicator.
2. You will not have an overdrive off indicator.
3. Wire A13 from the AT200/ST204 will not plug into anything which simply means your brake light won't come on when you're starting the car.
4. Rear foglights indicator will not be used since USDM Celicas do not have them.
5. I have no idea what the indicator is below the rear foglight indicator and therefore will not be used.
6. There are diodes in the rear foglight and mystery indicator circuits. You don't need to worry about them. No need to put bulbs in their sockets either.
7. B13 on the Japanese ST205 combo meter will be directly connected to the MAP sensor from an ST205.
8. Boost gauge circuit is not currently complete.
9. For the sake of simplicity, from here on out, both AT200 and ST205 connectors will use this scheme (as per USDM BGB):
A = 13 pin
B = 16 pin
C = 10 pin


Wires in the column labeled ST204/AT200 will need to be connected to the plug in the column labeled ST205.

Australian and European ST205 gauge clusters are different. The pinout information for them is below. The information used to create this part of the how to was from the ST205 BGB at CelicaTech.com

Yep. I made it myself using the pictures of the back of your cluster and the PDF of the USDM combo meter.
