I dont mean to hijack, but i grabbed the switch and delay box from my 89 donor truck, and was wondering if i can make this work with my 79 non delay wiper motor? Havent dug into the dash yet as mine is an a/c truck just wondering if anyones knows off the top of thier head.
Harryboxnoogle I know a 80 to 86 will work on your 79 never tried a newer one than that. You will just need to change the washer pump wire around but it will work. Only thing other than that is the shaft is about 1/4" longer but installed hard to notice that.
