The C.S.I. harness is a universal weather-proof engine harness providing wiring to accommodate the Charging, Starting, and Ignition of just about any non fuel injected engine. The C.S.I. harness is the Painless solution to repairing damaged wiring on your carbureted engine or for cleaning up the clutter and taking the guess work away from those swapping from fuel injection to a carb. This harness also works great as a engine dyno harness. Accessory circuits aide in re-connecting a factory fuse block, electric fuel pump, electric water pump, electric cooling fans, light switch, etc. Each wire is custom printed with the circuit identification as well as using GM color codes for easy installation.
