I am writing a pdf now to explain what happened complete with pictures and will post it here as soon as I am satisfied with it. I paid 179 plus FL tax from the Miami company. Free shipping and they pay for returning the core. They have three-four internet sites and they own them all plus they operate out of Davie Fl. They also sell on ebay. I called the number in the afternoon on the autocompluterexchange site. If you do it by phone processing is faster. I had my unit within 24 hours but I live in FL.
The IDM is located inside the drivers fender so you have to pull back the splash guard protection by the fender. It sets inside below the F250 on the fender.
I only tried to perform one buzz test. No buzz at all. haven't done the new one yet. Just happy it is running.
I will be ordering an ICP from White Bear soon. Mine is leaking.
