Message: [QUOTE="TARM, post: 678794, member: 578"] It was a wiper ground on the ones I have seen. Mine had neither issue. But others have. Its not that surprising given the age of these vehicles. My issue was a crappy grey ford CPS. THe BWD was night and day different in the smoothness and sound at idle and take off. Unfortunately I created a issue doing some testing and did not take it on the trip but the IDM fixed the high low codes and even before it the CPS swap took away a couple of the contribution test failures. They all disappeared with the IDM swap where before even when the IDM was still good I always had 3 failures using the grey ford CPS. Now with the BWD CPS I have none. My point is if you try the BWD CPS and have issues like engine surge or cutting out when your wipers are on I would first try isolating the wiper motor ground rather than go to a different and crappier CPS like the current ford IH ones. If the only issue with a CPS is that its sensitive to electrical interference trash the wiper motor is spewing out which it should not b4eing doing why not fix the issue rather than switch to a worse performing CPS just because it is more tolerant of poor grounding. When I get back from my trip I am currently on in a couple weeks I will try to take some step by step pics of the wiper ground and where to cut and splice and relocate the ground point. Frankly it seems like a good thing to likely do regardless given a electric motor can have these issues and if they are bad with the way its wired from the factory you can end up with a dead engine. Ford even did a notice on it I recall reading. [/QUOTE]
