Power lock fix in my 84 Van

When we bought our 1984 there was a hole in the door panel where a button was missing. I had no idea what it was. The manual and our copy of Chilton's was no help. I reached in and pressed the terminals. To my surprise the door all locked. Power Locks!! I spent several months trying to find a a button for the door but had no luck. The other day we went down to the junkyard that had two vans (an 85 and 86) and I pulled a lock / unlock button out of the dashboard. The plug in the back was different, so I cut it off to have 4 exposed wires. There was already an empty slot in the dash to the left of the steering wheel that it clipped into perfectly. When I took the door panel off, the 4 wires going to the broken switch where the same color so I knew I was in business. Running the wires back through the door and up to behind the dash wasn't feasible since they were pig-tailed off of the window control wiring. I traced the wires back through the door jamb and found where they came in under the dash. Then I used some in line wire taps to connect the correct wires to 4 one-foot pieces of wiring that I connected tot he button with butt splices. I popped in the key and... It Worked!! Pretty excited to be able to locked all 4 doors with out having to crawl throughout the van.
