so im doing a 5 speed swap. i bought a 84 trans am a while ago and took the parts that i needed out of it for my 83 dt500. im also changing the steering column so that it will lock the wheel with the lever by the key. anyway i swapped out all my pedals and clutch cyl yesterday put the column from the 84 in and was testing everything out. now the cruise control part from 83 was 3 wires and 84 was 4 wires, no big deal i can pull that out and change it, but my wipers will not work at all. now the signals work, high beam works, key works but the wipers do not work at all. there are 5 wires for the wipers and they are different colors from 83-84 but the plug in is the same. so i took my old assembly off my old column and plugged it in and the wipers worked fine so what makes the wiper switch different in the 2 years? is there any way i can rewire the plug in part so that i dont have to pull the column apart to change the switch out?

 

I've never done that but it's only about an hour job to pull the steering wheel, lockplate and TS switch to do the swap. Shuffling the wiring in and out of the plastic sleeve and through the column isn't bad if you take your time.
