ISB is your Dodge right?

The 5.9 I had in my 3500.
The ISL is a 8.9L in the MH.
The Pre-heat lights come/came on anytime I turned the key.

i suspect my controllers temp input signal has a bad connection, the glow light on the dash is now staying on for quite a long time even in mild weather, this would have been unplugged when they recently split the ck3 ans did the shuttle box rebuild. EDIT, came good,
