not even sure if it has dccd
the solaris s6 cant drive it directly its
needs a high current driver = small little circuit, if i wanted just to open the diff i could just wire it to the handbrake switch ie 1 click on the hand brake opens the diff witch would be ideal for manovering or wire it into the origianal controller. once set up i dont see why the dccd cant be controled by the CAL switch useing tps and vehicle speed ie turn switch to number 6(tecos carpark mode)
