That is fine. There is about 30 ohms of tolerance for each of the switch modes.

Was the ECM pin a genuine one that seated properly in the ECM connector?

Pretty sure it seated properly. It felt like it clicked in there. I'll try to pull it out again tomorrow morning and make sure it seats correctly. I would think if that were the issue the rest of the functions wouldn't work right.

The other one will only work after on/off works, so unless you can watch the cruise control input on a Toyota Techstream tool, you really can't tell if the other functions are working when on/off is now.

Right but after i get it on, everything works great. I used it from Chicago to St. Louis and back this past weekend to keep pace with traffic.
