I want to do this tomorrow morning, i have a 84 Z28 (2 speed wiper motor) there are 2 connectors going into it, the 1 has 4 plugs, one of which is hot (when the ignition is on for sure, didnt test with it off) i have all those wires. Then there is another on the end of the canister thing, with 2 plugs, 1 purple and 1 yelllow, that one was cut by the previous owner, i cant find the yellow, but i have the purple one...which is never hot. Can i splice into 2 other wires and just rewire this part to make it work? if so what do i need to splice into? (hot all the time,ign. on only, ect ect. Thanks.

Im looking in my manual, it shows the 2 yellow wires on the 2 plugs are connected and the purple one (the second on the 2 wire plug) goes to something else, its numbered 92.
