Default 2015+ WRX: Installing Shift light, finding Tach/RPM wire

Hi guys,

I'm trying to install a shift light, or rather it's an LED Tachometer (to help at the track).

Hooking it up to power was easy but there is 1 wire which needs to hook into a signal for the tach. Information seems scarce for 2015+ model, just a few threads on early 00's models.

- From what I gather, the methods for early 00's models of feeding a wire behind the instrument cluster won't work because you can't tap directly into any signal like that past the CANBUS.
- I found info regarding the *possible* pin on the ECU on engine bay but it's so well protected I'm not really sure how I would tap that.
- I assume there must be an "in cabin" location to tap that wire but I can't find any info on what/where I need to look.

Any advice is greatly appreciated. Thanks!

I'm pretty sure the Tach is using the CAN for it's datasource. Looking at the combination meter (dash) the Tach is connected to the microcomputer that's probably reading the CAN Tach channel.

I think your best bet would be to find a CAN compatible shift light.
