Painless Performance 24-Circuit 1967-68 Camaro and Firebird harnesses are designed as a direct replacement for your vehicle. These harnesses use a 1969 and newer style bulkhead connector design along with blade fuses and enough circuits to wire up just about any installed upgrade to your 1st generation F-body. Some minor bulkhead modifications are required. Factory original quick connect terminals are included for the in dash printed circuit board. Each harness includes a detailed manual and each wire is custom printed with the circuit identification as well as using GM color codes for easy installation.
