With it comfigured the way I've got (brake setup), I do need the always on -- in fact, that's about the only setting I use. BUT -- if you do it via the IVS, I wouldn't worry about it. Just a regular switch to arm it, off to use stock.
Which ever way you end up wireing it up ? You might think about wireing an (LED) light in the circuit so when you have it On.. the light is lit, to remind you it's on.
As you know.. things can get purdy Busy.. Shift'n gears, brake'n, change'n lanes and deal'n with Knuckle heads..... should you happen to forget to turn off the EBPV as a brake..... and >Resume< the CC ? You can Toast a Turbo.. Purdy darn quik
Roger that bigjoe, sometimes I wish the pete had an led in the circuit too, and there are 18 gears to shift while trying th remember to turn off the jakes! Thanks guys!
