Danger! ......... Yellow Box Wiring!
An owner has been in PM communication with me about this.
This person just had "gears" and a Yellow Box installed by a third party (both shall remain anonymous).
Driving home from the install and having driven only about 15 miles, his odometer clicked off 15,000 miles. I suggested that all the wires be confirmed to where they are coming from and where they are going. I suspect that the probability was extremely good that the YB ground wire was spliced into the ECU speedo input wire by mistake. Normally, this input is ony a fraction of a volt. By grounding the YB directly to the input wire, it is possible to send in as much as 14 VOLTS. The ECU most likely thought the car was FLYING!
DOUBLE CHECK the wiring and if something seems wrong with the speedo or odo, stop the car and pull all the wires from the YB. You'll get a CEL but at least, you won't rack up obscene mileage.
ps. The installer corrected the mistake and apparently was able to remove the 15,000 miles. However, he did NOT indicate how this was done and we should not be asking.
NOTE: This thread is meant to be a "heads up" and NOT to be used for flaming. Any such posts will be deleted. Thank you.
