85 turbo harness install on 86 regal limited

[jessecool]

I recently purchased a super clean 86 regal limited with a blown Olds 307 V8. And i own a rebuilt full 85 GN drivetrain harness and all. Now when i gutted the engine bay for the new turbo motor, I noticed where the harness plugs into the firewall to the fusebox. The Headlights and signal wireloom is incorporated on the old harness plug for the V8 and my turbo harness does not have this on the plug?..Do i need to some how cut these off the old harness plug or what?...does this fusebox even work for a turbo motor?
