FICM install

[powercat]

05 6.0 Excursion
Just had my FICM rebuilt (ficmrepair.com, premium ) and put on an Atlas 40 tune
Is there anything that i need to look out for on the re-install other that making sure the wiring harnesses are completelysnapped in and bolting it on?
Does the battery need to be unhooked? Any other gotchas?
thanks

Working on electrical or around the batteries, I always disconnect the batteries. That's just me.

Make sure all three plugs pop in place... when I installed mine I didn't plug my furthest one all the way in and had to tae it all apart again

its a really easy install.. push the clips until you hear a click and don't break the tabs!

Well, if you haven't already started this. You might want to look at the heater hose that crosses over the FICM. See if it is getting chaffed on the FICM. Might get a larger chunk of hose to cover it, or something similar, since you are in there. Those hoses have been known to chafe enough to cause a leak.
