Do need the ecm harness that goes thru the firewall on the passenger side. It keeps hittng my exhuast. Can i just cut it out or will it mess with my electronics

Are you using the ECM with your V8? Also, are you using your orginial instrument cluster? The speedometer feed and SES feed come from the ECM...

My motor is not using it but my cluster is

How badly do you need your cluster?

[Tink]

Is it damaged from hitting the exhaust? Could you move it or somehow tie it up?

Otherwise you could switch to a cable speedo or find another way to run a speedo feed...
