I bought a power door lock harness for my 1971 442. I was trying to figure out the extra wires built into the harness, come to figure it's from a 1970 cutlass that had the power seat back release, and rounded switches. For a 1971 442 do I need to get the square sharp switches to make it correct or did 1971 have the rounded switches ? I want to Thank everyone with info and pictures they posted for the power window install I'm going to be doing.

71 & 72 had the square switches prior to that they were rounded corners on the switches for the power windows and locks.

The power locks I purchased had a bad right side solinoid, and was missing the lock linkage rod. I purchased an AC Delco 11P3 actuator, and a set of linkage rods from ebay. The rods were close to original but definitely not the real deal, I used the remake rods,they actually worked out better then the original because I had to do minor shape work to it. The diameter was slightly smaller. using a mounting plate I made to mount the actuator, then that plate mounts to the three original mounting hole for factory locks. I only used the two bolts that are on the same side the other has a bolt with a nut on the inside,I used that as a guide stud when installing the mounting plate, I drilled out two 1/4 nuts that go between the plate and the door to give it proper spacing.When doing this you have to keep in mind you have to do both sides, the actuators work on a reversing polarity to function vs the factory solinoids work on a grounded housing and an up down wires. So at this point a rewire configuration is in order, which now I plan to get a wireless remote relay module.I will be posting more pics of it mounted.
