2018 Impala need washer hose from pump to cowl. Catalog show you have to go to headlamp wiring. I assume there is a connector package etc. NO get this you have to buy the Headlamp Wiring harness to get this hose
. Called Partech to confirm. Gal told me that it is in fact true and there will be other vehicles with this, I stated my utter dismay and she said " stupid isn't it"
