1993 Acura Integra Integra squeals.

Im back, you helped so much last time and I know u can help this time.

I recently got my motor swapped, and I installed a tach, but now my radio cuts off as soon as it comes on, its getting power because I can still eject and input cds, it just wont stay on and I cant turn it on, plus my tach wont work because its ran threw the ground wire threw the cd player, is it a ground wire problem or something else?

Now I solved that thanks to you I was wondering now, do I hook the green wire from the tachometer to the rpm signal on the ecu or the speed signal?
