just be carefull removing the grommet from the fire wall, you can use a mild dish detergent to lubricate the wires & remove them from the grommet, remove what wires you don't need from the harness (leave a pigtail on the connector incase you ever need to tap back into the ecu wiring) then reinstall the connector with what ever wires are left thru the grommet if there is extra space around the wires & the grommet doesn't completely seal you can use some heatshrink tubing to shim up the wiring harness to get a good seal on the grommet so you won't have any leaks.
