The current performance wiring was formed in 1999, when the LT1 engine swap was really gaining momentum and the LS1 engine was just hitting the market. Current Performance prides itself on top quality custom assembled engine wiring harness products. They follow OEM wire colors and use OEM connectors to produce the best quality at the best price. Current Performance's system is guaranteed to meet or exceed the expectations of even the most demanding show car owners. There, their wire harnesses are expertly manufactured using all new OEM connectors and TXL (polyethylene cross-linked) high temperature wire to common specification. Their spines go through a multi-step quality inspection process and all harnesses undergo continuity testing either through their Cirris CR harness testing system or by experienced quality inspection technicians.
