Hello all. I have a 98 Hombre 2.2 that came with no A/C and has no factory wires for a/c. I just installed a complete system from a wrecked 96 and would like to know what is the easiest way to wire this thing to work. I was informed that the ECM is probably A/C ready but i am unsure. I know these trucks are basically an S10/Sonoma but to replace an entire harness and fuse box is difficult as ones with a/c are not readily available. any direction will be great
