Cpteddie,
Both of them are excellent choices!
Haven't seen a small white plastic "T", two vacum solenoid/motors a long blue wire with a circuit breaker built in and a little plastic cheap box with two round black control knobs on it have you? Oh, and a three wire pigtail, yellow, red, orange too with a black 2 pin male connector around anywhere, have ya? (All heater "stuff".)
I know it's all in the shop, top shelf 3rd box over!
