my 68 roadrunner had a 2 speed wiper motor and I needed the 3 speed for air cleaner clearance , switching to air grabber type , so they both have the same 4 wire harness, brown red green blue , now for the switch the three speed switch has an extra terminal on it , when I was rebuilding my dash and putting the wiper switch and pump switch I noticed an extra brown wire on the harness, is that for the extra terminal on my new 3 speed switch , that's what I'm assuming that they wouldn't have 2 different harnesses for the wiper option, has anyone changed this over like me and know for sure

Do you need the clearance for a six pack air cleaner? they can be trimmed to use a two speed wiper

I put a high rise with the single 4 , got the base for the 440 because its lower but the top is what hits the wiper motor

I believe the linkage is also different on a 2 speed vs. 3 speed.

I trimmed the air cleaner back so I can use a two speed wiper.

Underdash linkage is the same EXCEPT for the nylon bushing in the crank arm
