Yes, the relay is available separately and a 70 amp relay is recommended due to the current draw of the pump motor ( W8002024 - Park Brake Pump Relay (70 Amp) In Stock / $41.92 ea 




Does this kit come with the spring for the hex adapter as well? ( Gerald Redwine, 08/12/2024 )
No, the spring is available separately however :

I have a 1995 Winnebago Adventurer 32wq P30/P32 chassis. Will the upgrade work on my MH. The upgrades state its for dates 1996-2000. ( Paulino, 08/09/2022 )
That will fit as long as you have the electric over hydraulic pump assembly that looks like this one https://www.workhorseparts.com/W8000498-Park-Brake-Pump-Assembly-With-Motor 
Does this fit into our Winnebago 2005 sightseer built on a Workhouse 2004 chasis?? ( Linda Repp, 08/27/2021 )
You would want the US21 kit for your chassis.
