I acutally kept my old valve covers, they were painted blue to match my car and would have looked a little funny in a grey cougar.

Sensors that I have to splice in:
Oil pressure switch
Knock Sensor
Crank Angle
Cam Angle
The one thing that has me worried is the intake, I'm hoping the idle control and the TPS run off of the same voltages. Then theres the EGR and the DPFE, I'm not sure how I'm going to do that just yet.
