Just disconnect the two connectors beside the power steering pump and the two at the rear of the drivers valve cover and connect the stock connectors back together at both places. You need to make note or mark the rear connector the vec2 uses so when you put it back in line you will have the correct connector of the two rear connectors . Everything else can stay but it wouldn't hurt to remove the ground (or positive) from the ground lug behind the front left tire...tape it up so it doesn't ground itself against something else. The rear is easier if you remove the cowl piece under the wipers......two screws on each end and wipers off to do that. BEWARE.....unless you have a boost retard to put on then DO NOT make boost unless you get at least 100 octane fuel. Normal NO boost driving will be ok.
