Dash Power wire?????

lets see if I can help you understand a little ..starting from the starter relay put in the fuse link or circuit breaker , from there run a heavy (10 gauge) wire to the NEW amp gauge, connect to the drivers side of the NEW gauge, next run another heavy ( 10 gauge )wire from the passenger side of the NEW amp gauge to the heavy black wire behind the old dash cluster, you can put both of these wires together with a splice connector.. this should give you power to everything EXCEPT the OLD amp guage .... I hope this helps, I cant simplify it any more than this...... the reason everyone wants you to NOT use the OLD amp gauge is because it has been the sorce of many problems in the past, including fires in the dash itself...
