I just did my euro swap and went from my stock 85 Cutlass harness to the 87 Cutlass harness. Everything works great and plugs right in with the exception of the windshield wiper motor. The plug on the side is still the same and works, but the plug on the bottom is completely different. The plug itself is different and the 85 has two wires and the 87 has three...is this bottom plug just for the sprayer motor or the wipers themselves. Also is there a way I can use this old plug and adapt it to this new one...just not sure as the new is three wire vs two. Thanks for the help!
