Does anyone have the POSITIVELY CORRECT throttle position and speed wires for AVCR?
I've STFA'd twice, and twice spliced into the pin on the ECU lead only to find out that it doesnt give me any information to the AVCR display.
has anyone done this install and found the correct wire colors for throttle pos. and vehicle speed? I have RPM and boost.
pics would be great if available.

These are the two I have tapped. Not working. WTF?
The car is sitting in place in neutral, but that should make a difference, should it? I know the speed wont work sitting still obviously, but throttle should, right?

Question..
The wire you tapped, is it part of the wires that go down to the 5 or so colored plugs near the back of the ECU box, where it opens up into the cabin? Or is this wire only present in the wires going to the plugs into the ECU?
Also, would grounds make a difference for displaying speed and throttle pos.? By it not working, I meant that it was showing 0 for both values, not that it wasnt turning on. The AVCR turns on and works fine and displays boost and RPM, but 0 for speed and throttle.

The latter, I tapped them from the larger plug set into the ecu....
Are there multiple grounds for the AVCR? What did you use for your ground i.e. tapped an existing wire or bolt on chassis?

I used the nut in the cabin, drivers side with like 4 brown grounds attached to it
I figured if it was a good enough ground for all those wires, it'd be good for the AVCR lol. the AVCR has two grounds, the green and black wires.
I tapped into the white wire with the blue stripe going down to one of those 5 colored plug in the hole to the cabin; I wonder if its the same wire? I dont see why it wouldnt be..

Here's an old post of mine with the pins I used.
<a href="https://forums.audiworld.com/s4/msgs/2385955.phtml">old post</a>
I connected the wires at the back of the ecu connectors and verified the pin number on the connector too.
I'd unhook the ecu and look closely at the connectors, there are little numbers indicating which pin is which, from there, verify wire color and follow them to make _sure_ you tapped the right ones.

Where on the ECU plugs are the numbers indicating pin #? I looked but didnt see any
are they right on the front of the harness plug where it plugs into the ECU? or on the back of the connector?

I used wires from the connectors for my Zeitronix installation.
The following wires was verified with Bentley and a continuity tester:
TPS:
ECU pin35 (ge/bl, 0.35mm2)
--> White connector T15, pin1
RPM:
ECU pin37 (gn/bl, 0.35mm2)
--> Black connector T10m, pin2
SPEED:
ECU pin54 (ws/bl, 0.35mm2)
--> Brown connector T10, pin3
Config of the four rows on main ECU connector:
6...24 (19 pin holes)
25...43
44...62
63...81
