Dash Cluster

[Ramiro0727]

I'm almost done wiring up my son's truck with a new wiring harness from American Autowire. Today I changed his temperature gauge on his dash cluster. When i took it out the cluster to replace the wiring. I cut some wires that were attached to the cluster. Would I have to reconnect this wires back up to the new wire harness? His original wire harness was like a rat's nest. i think that's why they added the wires on back of the cluster to make some of the gauges work. Can somebody tell me if the back of my cluster looks okay and if I can remove those wires that are attached.

thanks,
Ramiro
