what is going on? on 2000 Porsche Boxster

I had a new (used engine) put into my car and now the temp gaue and the radio don't work. It is an after market radio. Are they connected in some way. The temp does show on the diagnostic computer

It would be best to contact the repair shop that installed your engine. The computer has a separate temperature sensor than the gauge. Maybe you have a broken wire or a connection was missed. The radio not working should not be related to your engine replacement.
