After careful installation (making sure the plug is seated properly) it still is in limp mode and has the check engine light.
I also bought Carsoft v12, which seemed to work well with my super old Dell d600, I cleared the error codes, which were basically all related to solenoids. After a few minutes, the codes would constantly reappear. So I figure the plate is defective and must be returned to amazon.
BUT, before I do so, just wondering if it could be something else, like the Electrical connector/harness or the TCM? What's the best way to diagnose that? Could return the plate, get a new one, and go from there. TCM did seem dry, but who knows.

It depends on what codes you're getting. The most common code for a bad conductor plate is a turbine speed sensor fault. If you're getting solenoid codes then you need to look at those. the most common solenoid code on the .6 is the TC lock up solenoid. I don't know if those Carsofts can read actual values or if they show parameters. A conductor plate isn't necessarily the cure all for limp mode. Furthermore, those conductor plates that are suppose to be OE that come in the repackaged blue box, have been showing up defective right out of the box for the past few years. We aren't replacing that many anymore since we aren't seeing too many older cars anymore, but when we do, we buy them from the dealer.
