Hey all. This has been an exelent source of information for me so I thought I would share. I had a wiper motor failure and replaced it with a Cardone assembly. In the process of exchange I stumbled on a way of wiring this into my 72 without a relay and still maintains the park feature. 5 prong Acura harness orientation: Looking at the plug -5--4- -3- -2--1- 2007 ACURA Integra DATSUN 1: Low speed - Blue/ White 2: High speed - Blue 3: Ground - Black. 4: 12v constant - Blue/ Red 5: Intermittent - Jumper to #1 for Park signal Blue/Yellow is omitted from Datsun harness and not used. Blue wire on wiper motor needs to be cut and isolated on the switch side. Just needed to notch the shaft a little and it works flawless. Cost $72.00 Canadian taxed and delivered from E-Bay and there is very little wiring to do and no relay. Manufacturer Part Number: 76505-SR3-A01, 76505SR3A01 Reference Cardone Part Number: 43-1423
