I just installed 4.10's, and i bought a speedcal from SHM.
I know the dallasmustang speedcal you install it by the shifter somewhere. But this SHM one i got, you install it by the computer and connect with some of the computer's wires.
Anyone installed this SHM one before? The install looks simple in the directions, is it actually easy? And is this SHM one a quality piece?
guess i should've asked all this BEFORE i bought it, but im kind of an impulse buyer...
