I know that I need a PCM because the voltage regulator built inside is putting out over 18 volts going to
the battery, and causing the icons, and the odometer to flash on and off.
In the short term I wired in an external voltage regulator, as done by many others on the webb. It works,
but I would still like to replace the PCM.
My question is this: Are the suppliers that sell "plug and play" replacement PCM's legit? An example is:
carcomputerexchange.com , and the many others on the net. I notice that this company advertizes on
your site.
Thank you for your input. John P, Chesterfield Twp, Michigan
