stop light switch wiring RESOLVED
« on: October 07, 2015, 01:26:45 PM »
Hello All,

I'm a proud new owner of an Eagle that I just purchased and I'm in the process of driving her home yet I don't have brake lights....  Seeing how I bought car for virtually no money I wasn't worried about the fact and thought I'd pop new bulbs in on my route home.  But to my surprise its missing the entire stop light switch. 
I found a local store tha'ts getting the switch for me today but i cant find a clear diagram or schematic showing how its wired.  I know and have checked the fuse (which has power) but without tools to trace the wires and still several hundred miles from home I'm hoping someone can throw up a simple diagram showing which wires lead to and away from the switch (maybe the proper mounting for the switch itself as well) so I can install it for a safe journey home and avoid any ticket....

It's mounted near the top of the brake pedal on the pin that goes through the clevis from the power booster. There is a plug with 2 wires that go to the switch. I don't know if a car with cruise control has more wires. Sorry I don't have my car at work with me. If you have the package tray, you'll have to be small or a contortionist to get in there.

thanks fro the response.  I'm aware of where it goes, I have a fox mustang with a very similar setup.  I issue is that the switch is missing altogether....I'm getting one from a parts store and looking for a diagram or just color codes for the 2 wires that go to the switch.  Color? Are the wires together on a single connector that goes to the switch or 2 separate wires?  Again I'm trying to figure this out at a hotel parking lot....(:  Thanks again!

According to the 1988 Schematic there should be two 18ga wires.  One is Pink and One is Black w/White Tracer.  The switch is a normally closed design, so when the actuator is released, the contacts close.  The wire colors should be the same among all years but maybe not.

I'm at work but I can photograph the switch on mine and see if there are actually connector(s).  I would think there would be at least one.

Mine's on a single connector. I think the connector is brown if I recall.

If your car has cruise control it will have a 4 wire plug similar to the plug in Eaglefreeks pic.

Perfect and thanks guys!  I have a connecter just like eaglefreak posted to which I suspected to be the right one but it has a couple leads "rigged" to it going to who-knows-where.  I'm going to get it all hooked up and hopefully I'll be in business.  I'll post the results...

If I have some low amp accessory that I'm adding on, I often will wire it from the lead to the brake switch because its easy to find and it always has power.  Maybe the previous owner had the same mind set as me  ;D

Issue resolved.  The new stop light switch went in easy enough and the picture eaglefreak posted led me to the correct connector (pink w/ white tracer and blue w/white tracer both into one connector) to wire it up.  My connector confusingly was wired to run the radio, which obviously is more important than brake lights....So after the quick install we were able to make it home safely and I can start enjoying my new Eagle. Thanks!

FYI  At any common parts store they have assortment packs of "oil drain plug washers" for only a few bucks.  The size M14 was a perfect fit for the stop light switch shaft and it included a copper, steel, and a couple of nylon washers.  Obviously I used the nylon washers for each side of the switch and it worked out perfect.

I've got to ask why in the heck the brake light switch was removed? Was it removed to replace it and they got sidetracked? I just can't figure out why someone would remove the brake light switch.

I smell an evil plot . .

Glad you got it fixed and saved the car!

The brake light switch could have been mid conversion to the more common one or they may have been switching to Hydroboost. (or the lights could have been sticking on). Or there may have been a stainless steel tank in the back? ;)
AMC/Jeep gauges are for amusement only. Any correlation between them and reality is purely coincidental!
