Power Seat relay
I'm re-wiring a car that uses Olds Calais seats, the drivers seat being power. The existing hacked-up factory harness uses a power relay wired so that the accessory switch must be on before power is applied to the seat motors. I suppose that the GM engineers don't want their drivers to move the seats when the car is not running. The relay does not keep heavy current from running through the switches, just keeps the seats un-powered until the key is turned to the ACCESSORY position.
I see this as an unnecessary complication in a street rod and plan to do away with it unless wiser minds than mine on HRB believe that misfortune will befall me if I wire the seats like I have every other car I've built, i.e. with a 30 amp fuse powering the seats all the time.
Other than pissing off GM engineers, am I thinking wrong?
