Default Hood Tac Wiring Question

My hood Tac seems to work..... But, only when the wipers are turned on!! This is a 3 wire repro tac, so I assume that 2 of the 3 are good, but that the one that looks to be wired to the wiper motor is not going to the right place.

Can anyone explain to me like I am a 5 year old, were the 12v key on power wire needs to go?? Pictures are also extremely helpful.

At first, I thought it was a bad ground and that maybe when it rained the water was making the connection and allowing the tac to work, again. The other day, I bumped the wipers on in dry conditions and lo and behold, the tac worked!
