they are no dumps(normaly open) as apposed to regular nc(normaly closed), so they close the accumulator off when powered, wire them to to your solinoid(switch wire,not power) so that everytime you hit the switch it closes the accum off so that theres no loss in speed,then opens back up when the they arent powered giveing you the good ride
dumps are normally open... but when you hit the switch to cut off the accumulators you'll burn out the dump-solenoid they'll heat up seals will start leaking all over the place. My brother had 4 on his 64 & on the 1st night out cruising seals went out from the heat on the dump solenoids... I guess they'll work if you plan on just cruising 99.95% of the time & hopping & fucking around for just .05% of the time. But if thats the case go with airbags.
