Welcome to the board! Great to see you here. I see that a couple of the fellas with a terrific knowledge base have responded to your inquiry.
That immobilizer/ecu... whatever... feel around for that damp. Maybe give us some background about your purchase.
Oh! Clean out those drains. Me? For each drain hole I pour in a half cup water paying attention to how much exits underneath the car. Further, when I have the top in service mode always, always I pull out the vaccum (with blower option)... position the hose to the top of the drain holes... and let it blow out any debris (I don't own an air compressor). I've read too many horror stories about negelected drain holes... and it only takes a few minutes to clear those drains.
Again, welcome to the board. Enjoy the reading! See ya around.
