I have 2011 MC base with N16 engine I'm having a problem with thermostat lead adapter. The engine had the oldthermostat with just one plug port on the housing and one plug for the temp sensor inside the bleeder screw. I installed the newer OEM thermostat 11537534521 with the adapter 12517646145. However I plugged in both plugs in the sensors and the lead adapter 4 prong female plug at the end I don't know where plug into now. I watched multiple videos nobody covers this part of installing the lead adapter and all its connections. please help.
