HKS Type 0 TT install...help..

[HailtotheSilvia]

hey guys, just got a HKS Type 0 TT but doesn't come with instruction, don't know why..(only have japanese instruction). I also have the Harness for plug and play install. Here's my question. I know there's 2 wires that need to be wired in with the parking break and the tach. There's a grey wire and the brown wire...where do they go? Thanks a bunch guys, any inputs are appreciated.

Harness plugs into igntion wires at steering column.

RPM wire goes to ECU RPM wire

Parking brake wire goes to black wire on the parking brake
