Hey guys. Been doing a swap on my 99 2.5RS with a 2005 STI cluster (GC8 to STI cluster swap). Here's what I've been using:


and here's the pinouts I've come up with:

Code:
Function		1999 RS Pin	2005-07 Sti pin
N/A			A1		
Coolant Signal		A2		A11
Fuel Gauge		A3		A3
??? 			A4		
???			A5		
ABS Light		A6		B3 (Reverse Circuit)
Low Fuel Warning	A7		n/a
???			A8		
???			A9		
Coolant Temp Ground	A10		A10
EBD (Ground this wire)  n/a              A2
			
N/A			B1		
N/A			B2		
N/A			B3		
N/A			B4		
Door Warning Light	B5		B13
Door Warning Light	B6		B14
Seat Belt Warning LightB7		B9
Illumination +12V	B8		B24
N/A			B9		
N/A			B10		
N/A			B11		
N/A			B12		
Turn Signal LH		B13		A9
Airbag Light		B14		B18
Turn Signal RH		B15		C3
???			B16		
			
Headlights +12V		C1		B30
Hi-Beam Light		C2		B29
Illumination Ground	C3		C6
Illumination +12V	C4		C8
N/A			C5		
Park brake/fluid light	C6		B19
Ignition +12V		C7		C7
Constant +12V		C8		C10
Tach RPM/ECM		C9		C5
VSS			C10		C2
N/A			C11		
N/A			C12		
Turn Signal Ground	C13		B4
Oil Press Warning Light	C14		B2
N/A			C15		
N/A			C16		
Charge Warning Light	C17		B1
CEL			C18		A6
The major issues so far that have been resolved:
E-Brake light fix: A2 on the STI cluster must be grounded. This is input from the EBD. Without it, the brake light stays on. With it, the light comes on when the brake is pulled. P.S. check the spring/switch on the handbrake. Mine wasnt going into position all the way and was driving me nuts (false positives/negatives).

ABS: this is a reversed circuit on the STI cluster compared to the gc8 one. When the GC8 abs circuit is grounded, the light comes on. On the STI cluster, when ABS input sees +12V, the light comes on. Simple relay reverse circuit was used to fix it. AS outlined a few times in the thread.

Hope this helps a few people.

Im looking for a direct bolt in a usdm STI gauge cluster for my 05 STI. I heard you can use a usdm 04 and 05 cluster but the 06 and 07 cluster is slightly different, can anyone verify this?

05-07 should work. They have the 16 pin left connector. The 04 is 14 pin and the abs function is reversed. I don't have the 05 diagram, but 06-07 do have a wire in A2 that might have to be grounded when in your 05.

anybody know anything about swaping the 2018 cluster into a 2017?
I really like the look of the white and red together

Default Impreza RS to STI S202 cluster Swap

Hello, I have a 05 RS and recently bought a 02-03 STI S202 cluster and would like to know if there is anybody that has done the same thing (Impreza to STI cluster) that could make this any easier for me?? Any information about the plug and play or just rewiring it. Like is it just plug and play? My RS is manual.
