MSD Coil Harness
PVC vs TXL "crosslink" Hi, you have a correct observation.
The MSD PVC insulated wire is thicker due to LOWER dielectric strength.
The PVC will MELT at lower temperature than OEM GM wire.
MY "sub-harness" IS an upgrade, we use Crosslink insulation wire with a TXL size.
I found this necessary due to Under Hood Temperatures of BAJA race cars.
