You may have to try and calibrate the motors, or set them a certain way.

Quick fix, I figured out what the problem was, pin from temp sensor was not making connection with the back of the control unit. It needed to be pushed in more. These AMP connectors are little tigther than the OEM connectors. 18 Guage wire is too thick and 22 Guage is to soft to fit them in. I guess best wire is 20 awg.

Its working good now.

When it comes to the Relay socket regular socket relay is not going to work. I ordered one and no good. So I 3d printed one relay socket, used 9mm male and female slip on connector for the thick relay terminals on both end with a wire in between.

The original relay socket Randy used is only available in Europe. I probably should have ordered it, instead of relaying on eBay relays. At the end 3d solution worked just as well.
