I traced the ground wire from the ac relay under the hood fuse box and the ground [or black] wire coming off the ac compressor and both wires seem to go to a splice that's inside the engine wiring harness. [Pictures attached] I'm instaling ac in a non ac truck so my question is can I ground these wires anywhere else when I put it inside the truck and if not does anyone know where I can get another one of these metal clips??
