I was able to get an older Hot Springs Grandee model g hot tub. We can not figure out the wiring. We had a tub installer swing by and he wasnt quite sure and asked for the tub owners manual or wiring diagram. I dont have these and was hoping one of the experts here could help. The tub has two big wires blue and red. Then 3 small red, white and blue. If anyone has an idaea or knows please letr me know. Thank you!!!
