Vehicle Speed Signal - Finally an answer!

Good post. I just installed my EVC6 last night, replacing my EVC5 so I could have boost by speed.

I will add to this. I did not want to remove my cluster to get to this 2 pulse speed signal wire, so I followed the wire in the service manual to see if it went somewhere more convenient for me. It did.

Behind the glove box, top and center, is the Power steering control box. Pin 8 is the same wire. Its in the second position in the second row, the blue wire.

Be careful, its barely got any slack from the harness, and its a rather small gauge. So if you broke it or accidentally cut it when trying to strip it, its hard to solider or crimp up in there... I know because I broke the wire and had to do this LOL.

Anyway, worked out perfect for me and it was already in the path of where my EVC wiring was passing by.

I got the throttle position signal for the EVC6 off the .5-4.75 volt output from the accelerator pedal. I went for this wire straight at the ECU main connector.
