'93 Voyager LE; Wipers won't work, motor is ok..???

I am hoping that someone can help me find where the 'RELAY' is for the windshield wipers on a '93 Voyager.

My windsheild wipers do not work andI had a mechanic check it out. He said that the motor is fine and I need to replace the "RELAY".

Well I bought one from Kragen, but know one knows where the heck to put it! I can not find the old relay and Chilton's is not a help at all.

Thanks!
