ok, my 90 civic came with an aftermarket cass deck from ages ago.

which wire do i hook up the remote wire to, to run an amp?

on newer harnesses i believe there was a blue w/ white stripe that was for the remote. and i know i don't want to use the red, cause if the stereo is off but car on i don't want the amp on. i'm thinking i should use the blue power ant wire, but need to be 110% sure.

grey & white - front speakers

purple & green - rear speakers

red - ignition power

black - chassis ground

yellow - memory power

orange - dimmer

blue - power ant. (my car doesn't have a power ant.)

 

You can never be 110% sure, only 100%. And to answer your question, yes, use the power antenna wire.

 

thanks for the humor, i needed it. and thanks for answering my question too.
