im about to purchace an hks turbo timer and i just have a few questions. would i have to get the U.S. standard or the metric measurement one? (the black or the silver) or does it not matter? lol and also, do i have to purchase the universal harness or can i hook it up just the way it comes in the box? thanks guys and gals, any information would be very helpful lol

 

get the us (metric should be in km/h and not mph). also, theres no scion tc harness, you will have to splice wires yourself. dont worry though, its only 6 wires.

 

ok awsome man, tyvm, so those 6 wires jus come with the turbo timer itself or do i have to buy them seperate, do you or does neone else know?

 

The wires came with the timer. Did anyone has the installation instructions?

 

iirc, there is +12v, ground, IGN, speed sensor, engine speed sensor, and ebrake.

i love mine btw, type-1 :D

 

type-0 only has 4 wires to splice.. just for reference
