You can get 12v from anywhere you like, i use an Add-a-circuit in the fusebox though i don't know if you can get those locally. You could get 12v off the ignition, stereo, wherever you like. The ground can be anywhere as well though it's best to ground at the stock ECU location at the throttle body for things like that. Not sure how much that matters with the knocksense.
The knocksense has instructions for the LED, i mounted mine on the steering column cover so i can see it easily. The TIM wire should be connected to the KNOCK wire that i labeled on the MS harness. You will be able to see the KS pulling timing in the datalogs.
I'm still no guru, i just spend too much time online.

Ok, got it. Just with the stock ECU's ground by the throttle body. My LED is going in an extra hole they made on my 2 gauge pod (the ones you hate:gay above the gauges which is basically in front of my eyes!

The part of the MS harness labeling I had already seen; BTW, great job, the only thing I would need would be for you to write it in Spanish next time

hey guys, ive also found this which is big with the wrx market here in australia

http://www.linkecu.com/products/Anci...ices/KnockLink

KnockLink is an LED bar graph display designed for monitoring engine noise, particularly engine knock (detonation / pre-ignition). KnockLink can be used with almost any type of factory knock sensor and has a built in sensitivity adjustment to allow the display to be tailored to any application and engine noise level.

Most modern engines will already have a knock sensor fitted as standard, but any type of knock sensor may be fitted as required. The sensor is normally screwed into a boss on the engine block although some manufacturers fit the sensor in the inlet manifold (especially Ford). In either case, the sensor must be in such a position that block vibrations are coupled to the sensor.

Assuming the engine is operating correctly, the LEDs will show only background noise which will rise in proportion to engine power output. Any abrupt rise in signal level at any time is an indication that detonation is occurring. Early detection of severe detonation can help prevent engine destruction.

Whether installed permanently or used as a temporary diagnostic tool, the KnockLink can help detect detonation / pre-ignition, optimise advance and prevent costly engine failure.

u.s $113
euro $83
Aust $136
kg 0.3

i think its also well priced, what you guys think?????

when i was running 87 on my 01, i would hear some knock during some spirited drives (corners that dropped me out of powerband)... i'd hear it once or twice, then it shuts up... which can only lead me to assume that the knock sensor picked it up and retarded the timing...

now that i decided to invest that extra 15 cents for 91... it doesnt do that anymore
