I am trying to find the wire that sends the speed signal into the ecu cause my speedo does not work and it is confusing the computer telling it to cut fuel at like 90 miles an hour. Need some help!!

from what ive been told, where the wires are, (underneat the passenger side i believe) are 2 green wires and a yellow one... and you cut the green wire that is not doted. that should get u up to 124mi/hr max. the only problem is, is that your engine sign will be lit, but its normal. double check with someone else on this.

On a 93 the wire that connects the ECU to the speedo is a yellow/green wire.
