200WRX.GP

I want to install an HKS Turbo Timer in my MY03 WRX. Could someone please tell me where I can connect the RPM and Speed sensor wires. I would prefer to stay away from the ECU pins, but if this is the only option then I will do it. I got the MY02 pinouts, but the wiring colours they mention don't match. Which pins / wires should I use, and how do I test to make sure I have the right ones?

Thank You
Michael

Have yo looked at the back of the speedo?
There should be everything you need there

I'm sure it is, but there are lots of wires there, and they just plug into a PC board, so I have no clue which ones I need.

Thanx

I only have experience with my MY97, but on the PCB is printed TA and SP next to a couple of the screws holding the flexible PCB in place.
I used these for the Defi speed/revs display.
Just used the screw with a ring tag underneath.

TA = revs
SP = Speedo
Theres also a + and - there too

Hope that helps.
