Hello everyone,

I need your help.  I bought a damaged 2002 is300 and have a couple plugs on the front end that I don't know where they connect.  I have scoured the Internet but can't find a good pic or diagram.  I assume that one of them goes to the wiper fluid pump, but am not sure.  any help would be appreciated.  The 2 plugs are on the same harness as the horns.  thanks in advance.

Hi Eric...welcome to the club

As you say, they are probably for the washer pump but maybe also an ambient air temperature sensor possibly.

Let us know what you find

Cheers   Trevor
