ground side for the valves?

does it matter which terminal i use for the ground? i have asco valves if that makes a difference. there are 3 terminals and only the top 2 get used and i didn't really pay attention when i pulled them off. thanks.

makes no difference.

thanks man.

just make sure however u do them that u are consistent on all of them say up have ur negative on the left and your positive on the side, keep then like that on all valves...

yeah.... ^^ true^^ cause if you do it any way then you might get confused.....i would justgo:
hot - right
neg - left
