Driveshaft is built & installed.
New Radiator with Oil Cooler, This truck originally had the light duty (narrow) radiator. A HD (wide) radiator bolts right in.....Just had to use a matching fan shroud.
Installed a factory ('99-'06) Auxiliary Trans Cooler. Had a cooler line set to match. Basically the front section is GMT800/4L60E.....And the rear section is K2xx/6L90E. Cut off all the factory crimps & married the 2 together using Trans Oil Cooler Hose & ear clamps.
Wired the A/C Compressor controls a little different than factory.....
Installed a High Pressure cut-out switch in place of the K2xx pressure transducer, Wired the High Pressure & Low Pressure Switch in series to the ground side of a relay coil, Power side of the relay coil is controlled by the A/C Request signal from the control head.
Started marrying the K2xx engine harness to the GMT800 fuse box & body harness, Not difficult just tedious & time consuming. Had to crimp new terminals on all the Ignition Hot circuits to fit the GMT800 fuse box connector.
