I'll check that fan wiring, I'll let you know on the AE as well. I needed to upgade since i take care of 6 vehichles 4 of which are OBDII. None of them are as tricky as my superduty though. I love my truck though. I got over 200k before having any real trouble.I did the blue spring update and changed to a fleet coolant when I got it and that is the only major work I've done prior to some major wrenching not that long ago.Yeah, that fan harness is what I getting at -- it likes to rub thru on the fan shroud and then back at the engine where it is supposed to be tied
If the fan harness shorts out it will kill the engine
AE is a nice tool, but I would have recommended ForScan for your laptop -- just as nice and a lot less expense -- and the BAFX or ObdLink MX adapter
Let us know how well the AE works out -- I been thinking on getting it so I can be more helpful on the forum, but the cash is not there yet .
