hks Turbo timer type 1 install

[Sean WRX]

I have just purchased a new hks turbo timer type 1, (timer plus other features), Ive looked on youtube for installation instructional videos, but i dont want to start the job until im surularce of what i am doing. My main concern is splicing the wire to the ecu rpm and vehicular speed any tips? is it advised to take it to be done by a subaru speicialist

You need to find a pin out diagram for your number ecu, have you had the carpet back in the passenger footwell ?
