Trying to find just what plug under at the transmission is the reversing lamp switch - Im having a fault at my reverse lights, they have been flikering off and on - and I am pretty sure this is the culprit - they just stopped working, and most of my driving is at night - hard to back up with jsut red tail lights



If you can tell me the location that woudl be fantastic - is it screwed directly into the transmission housing on drivers side or passengers side? Near the top? Thanks ahead of time! Need to get this thing fixed ASAP! :-)

 

All manual trans sensors are on the driverside of the trans. If I recall, there's only two sensors on the 01+ M5od's...one for speed and one for shifter position. Take a peek at the one way up top by the base of the shifter. Look for a black w/ pink stripe wire or vice versa.


I havn't my wiring diagram in front of me, this is all memory. Gotta find that book darnit. lol.

 

Hmm Ill go out and crane around a bit - Thank god for bodylifts - this would be a major PITA without one.. going to clean it out, spray some electrical cleaner in it.. see if it works.. and if it doesn't I will check for continuity

 

gimme a few mins Mike...I found my big book and am looking at diagrams on the net right now.

Wire color is Black/Pink for reverse lamp hot. The other wire on the sensor is Violet/Orange.

Looking for sensor location as I type...

 

Alright, I am pretty sure I found it... big 3/4" nut plug right in the top of the tranny drivers side near the shifter... checked continuity and there was nothing there so I'll have to go order up a plug - not surprised.. my reverse lights have been flickering off and on the past week, guess it finally went out! A confirmation woudl be great if possible.. Although I'm pretty sure its what it is.. searched up a few pictures on what it looks like and I'm like 80% positive :-)


Thanks by the way, Shane!




Just hope Nappa has the part in stock down there.. ugh, I hate waiting 3 or 4 days for parts to be brought in..!

 

Yup....that's the sensor.


Found a pic from Trevor's manual swap showing it...(top of pic)...

 

Perfect! The red gave it away, yeah, thats the one I pulled and checked for continuity; nothing at either terminal in there so I'll go ahead and order up a replacement over at nappa in the morning.


Thanks bud, I was hoping a picture woudl be in order - it helped to confirm it!


The onyl other thing it could be if this isn't it - is the sensor in the shifter itself that connects when it clicks into reverse.. but lets hope I dont have to dig into that :-S

 

There's a push rod between the shift rails and the sensor itself. Sensor unscrews out the trans, then you'll see the push rod in there...or it'll come out with the switch. Push rod pushes out on a roller ball on the switch when you shift into reverse, signals the switch, and in turn turns on your reverse lamps. I don't recall if the ball moves towards the trans or away to set the trigger...but you get the point I hope. lol.


Just by chance...I mean I know you did....check fuses?

 

Yup, checked the fuses, #27 on there, plus any around it.. All of them are good!


The first sign I was having a bad connection was my LED reverse lights were flickering and barely lighting up.. I think the switch was starting to get corroded or something.

 

I had the same problem...

Awesome! $24 later at Nappa and all of 2 minutes to pull out the old and pop in the new.. the problem is fixed! Reverse lights are workin as good as ever now.. woohoo!
