my reverse lights died, i doubt its both the bulbs however i will check... is the reverse light switch internal or external? anyone change one?

 

On the transmission...

 

It's the one (for 5th & reverse) with multpile wires on the top left rear half of the tranny.

 

jsut feel around the tranny there aren't many
wires on it mine just came loose one day, I
also backed into my buddys 7 that night lol.
anyways you should be able to notice a loose
wire and get it back on. Matt22

 

Mine does the same thing but it looks like all my wires are connected, I know its not the bulbs because they worked before I swapped them over from my old 7. Is there anything else it could be?

 

I just went through this problem in December. The lights were all fine and there was power at the switch, but no reverse lights. Turns out that the switch on the tranny died.

Check out the FSM steps for troubleshooting the reverse switch. This will tell you if your switch went bad.

 

is the switch easy to replace because i have a parts car

 

can someone take a picture of it? or describe it a bit? my switch is broken so the reverse lights stay on all the time, I need to just unplug it for now cuz I've already gotten a warning from a cop about it!

 

The T2 tranny is on the right (GSL-SE on left).


The backup light switch is the large brass looking cylinder with red wires coming from it (near the top). Maybe you can loosen it from below but looks like it would be a bitch to get at. It takes one real big wrench to loosen it if it's on real tight.

Good Luck,

Scott

 

thanks, I'll have to try this out tommorrow

 

yeah i checked it out, power at the switch but not after the switch with car in reverse, im going to see if i can take out the switch now.

 

so the part is 35 from pep boys and 126!! from mazda. ouch. i guess pboys is the way to go

 

I just had a manual swap as well and my reverse light is not working either. I had a friend help me troubleshoot it with wiring here and there, but it didn't work. I want to try this "reverse light switch" swap, but I don't know how the unit looks like. Any pictures would be helpful ...

Excerpt taken from Rotaryressurection.com

wire reverse lights. Find the 2 red wires on the switch on your 5sp transmission.

If working with an 89-91 car, find the 6 wire plug near the starter, and the 3 wire plug near that. ON the 3 wire plug there are 2 pins together and one offset; run a wire from this pin to either of the red wires on the trans. On the 6 wire plug, locate the bottom row, center pin; run a wire from this pin to the other wire on the trans.

If working on an 86-8 car, there should be a 4 wire plug by the starter. Connect the 2 right side pins to the 2 red wires on the trans.

 

LMAO this is my friends original thread from 7 years ago. Oh boy I gotta show him this.

 

 

Can i still use the same reverse switch on my 87 if its an automatic transmission? They all say manual

 

The reverse light switch (8130-17-640D) is NLA from Mazda. Atkins Rotary sells Mazda reverse switches (https://www.atkinsrotary.com/store/8...tegory_id=1093) for $36.50. Usually, the switch will develop a high internal resistance and stop working. Also, check the electrical connections at the switch harness. I once had problems with the switch not working and the problem turned out to be corroded electrical connections at the switch.
