Hi,

Am trying to Locate the ECU and the the harness to locate the following 3 Cables:

Power
Ground
Feed from the ECU that Gives Speed.

Any help appriciated..this is for MY98 UK Spec Scooby....

I have these on my PC at home, unfortunately I'm not going to be there for 3 days

There is a STi V3/4 pinout on the Ravensblade site, power/gnd/road speed input/rpm feed to dash are the same as a UK car.

When you say speed I presume you mean road speed from the gearbox pickup? This is fed to both the ECU and the dash clocks in parallel from the gearbox sensor, unlike the engine speed where the sensor signal goes to the ECU which in turn drives the tacho.

Andrew,

I belive that is the one...I am trying to connect my Blitz Power ID Meter, and have been told i need to tap into that wire....

Have not had much luck in finding this info, so will drop a post if i do locate before hand...

Where is the ecu located?

Thanks
Sam

Just found some notes on my PC at work:

B135 (16pin connector) pin 3 = Vehicle Speed Input

B136 (22pin connector) pins 1&2 = Main Relay +12v
B136 (22pin connector) pin 12&13 = Ground

Andrew,

Thanks for the info...I will atempt to locate the wires this this evening after work...

Is it ok to assume, after i locate the ecu, there will be marking for me to locate the cable labbled B13* for the 3 cables? Or is it little more complicated then that?

There are 3 yellow connectors going into the ECU, B135/6/7. They are all 2 row with 16/22/12 pins respectively so you can't mix them up.

The power and gnd connectors are next to each other (as its a 2 row 22 pin connector, 12 is below 1 and 13 is below 2).

The diagrams I have at home make it much clearer than I can in words.

Just spoke to Rc Developments, who supplied the ECU for the car, and have been told that the same wiring diagram is used as the standard ECU, as it plugs straight in..

So will go down now and try to locate the road speed wire...
