View Full Version : ST202/ST204/ST205 (BEAMS, GT, and GTFour) cluster pinout and rewire

06-22-2014, 11:44 AM
Ok guys, I've been working on some repin instructions for swapping in the ST202 BEAMS and ST205 GTFour cluster (same pinout in these). I've mapped out the cluster from a 95 Celica GT Convertible (my stock ones), ST205 GTFour (unknown year), and ST202 BEAMS A/T (unknown year). Pictures with the lines drawn over the circuits are below.

Excel spreadsheet detailing pinswap in google docs link here (https://docs.google.com/spreadsheets/d/1H5gVPquBmE7tVSY8cMrIAfo5EbYNKGiDQVxZ92L9XLE/edit?usp=sharing),
anyone can comment, only I can edit. Please comment if you notice a mistake I have made. Also let me know if it's confusing or could be explained better. It's a lot of info I'm trying to organize into the spreadsheet. I would prefer comments in the spreadsheet and not in this forum, that way I don't have to flip between the two.

The reason for this, I want to use the full gauge set for extra indicator lights (A/T circuitboard is completely separate from the gauges with exception of power and ground)

There will be a youtube video soon.

I could use someone to look over the spreadsheet and tell me if it all makes sense, that way I can be at peace about other people looking at it to decipher it.
