I'm looking for the same digram to hookm up the rpm wire on my HKS turbotimer. HKS doesn't have the 2004 STi ECU wire digram available yet!

Sub tech. An HKS turbo timer should be standard issue on all Sti's to protect that maxed out turbo from coking if shut down hot. Unfortunately, Subaru hasn't seen the wisdom of this "non performance enhancing " mod yet and are being real PIA's about getting us a simple ECU wiring diagram so I can use the auto feature based on rpm recently achieved during driving. Subaru is new to the performance arena and needs to realize that some mods are actually smarter than stock! Even Ford's SVT division is relatively leniet on mods as long as they don't overstress stock parts.

ok i found out which one it was and i already pmed (ddsski) it's the 23rd pin on the 34 pin harness on the far left of the ecu. so it goes
(B134)
7 6 5 4 3 2 1
17 16 15 14 13 12 11 10 9 8
27 26 25 24 23 22 21 20 19 18
34 33 32 31 30 29 28
so it's # 23 (B134)that is your RPM now using that #system on the next harness #27 on (B135)is your speed. and 1 and 4 on (B135) are your ground. and on the far right one # 15 on (B137) is your ignition.. and #33 on the far left(B134) one is your AF + sensor. so it goes
B134 B135 B137 B136
34 pin 35 pin 35 pin 31pin
Hope this helps all of you..
