"do no invert in cold/hot inlet. You'll end up with a flimsy spray rince due to the hot water restrictor since spray rinces are cold (spray rince could already be longer/better than what it is now) and that will make you want to use a 2nd rince."
The spray function is actually during the spin cycle of the wash cycle, not the rinse cycle although it is a cold water spray regardless of temp switch setting. With the wiring mod, if your temp is set to warm, you would get a warm spray with both hot and cold valves on which would give the highest amount of water for spray. If you want a hot wash and warm rinse, you would need to change the temp switch over to warm directly after the washer has finished filling with hot water in the wash cycle. If you really want a hot rinse, you would then need to switch back to hot sometime between end of spray and beginning of rinse fill.
