Hello all. I have looked on the forum and searched for an answer to this so if it has been asked just push me in the right direction. I have owned a few 6.2 diesel suburbans in the past and have decided to upgrade to the 6.5td. Picked up a 95 k1500 suburban with new 4l80 trans and 165,000 miles on the cheap but it had no motor. Found a wrecked 98 k2500 and got the motor complete minus starter for 400. Putting the motor in and most everything seems to plug right up. What issues will I run into with using the newer motor in the older truck? It seems the 98 motor has a few "extra" connectors that the 95 harness does not. Will these make a difference out will it just run as an obd1 without these? Any issues that would cause the vehicle not to run? Any help or advice would be greatly appreciated. I am aware of the pmd issues and will be installing a remote mounted pmd with heat sink. This will be our next family vehicle (replacing 02 Montana) so I don't need a lot of power mostly shooting for reliability over anything.
