Default STi gauges in '05 WRX

I'm looking to upgrade to the STi gauge cluster in my '05 WRX. I was just wondering if anyone knew whether or not it would work. I've been able to find a wealth of information about installing '04 STi gauges in the '02-'03 WRX, and a little bit about installing '04 or '05 STi gauges in an '04 WRX. I haven't been able to find anything about installation in an '05 WRX.

Does anyone know if the '04 or '05 STi gauges are better compatible with an '05 WRX? And then, would the install be the same as an '04 WRX?

Thanks for any help you guys/gals can give me.

I sent this to another member asking the same question.

I have a 04 cluster in my WRX. The only thing I changed was I moved the cruise light wire from one pin to another. The 05 WRX has it on pin B28 and the STi has it on B16. The ABS light works backwards with the 04 cluster (they reverse wired it for all 05 models for some reason) so the light stays off then comes on. This little thing can be fixed by using an 05 cluster, but you'll need to switch more wires on the cluster as the fuel level and temp wires are in different positions in the 05 STi vs the 05 WRX.

Using the 05 STi cluster will have the ABS light work right, but you'll need to switch more wires. The 04 cluster will only have you switch one wire, yet you'll have the ABS light work backwards. It's up to you on how you want to approach it.

The outside temp inidcator will work since the WRX has the auto A/C so you won't need to fabricate any wires for that.

As for other lights that will be on, the I/C waterspray light and diff temp lights will be on, as well as the DCCD lights. I put black electrical tape behind the cluster faces (lifted them gently and used tweezers) to cover the lights.

Two last things, First, it's rumor that I have not been able to confirm, but some say the 05 cluster has different plug sizes. You might want to find a friend who has an 05 and confirm this if you decide on an 05 cluster. Second, people with JDM clusters seem to have a problem with the loud buzzing noise coming from the shift indicator. I don't know what causes this, but i'd stay away from the JDM cluster.

Other than the lights, and the wire, the 04 cluster works perfect in my car. Rev light, beep, sweep, and temp.

If you have any other questions, feel free to ask.

basically true, nice write up, an 05 will work the same as you 04 except for that plug you mentioned. it will fit with a little cutting of plastic so theres your answer! an 04 sti cluster is the best bet!
