Today I'm setting up the 2 step feature on my Holley Sniper EFI with Hyperspark Ignition.

This is on my 1990 Third Gen Chevy Camaro with Vortec Heads, Shorty Headers with a dual 2.5" exhaust running to Thrush mufflers.

The install is very simple all you need to do is locate the orange or yellow wire from the 10-pin harness from the main body of the Sniper unit then splice into one of the wires and run that to one leg of a switch. on the other leg of the switch run a wire to a ground somewhere on the car. Easy as that!

Setting it up on the handheld is as easy as turning on the feature and setting your rev limiter rpm and which input you would like to activate the 2 step with.
