so, i just found out that my reverse lights are not working. checked fuse, bulbs, are good. however, have no power from wires to bulbs.
not sure where the reverse switch is on tranny.
i think it might be that switch. it's a b16 tranny but from another si. not sure if the previous owner installed/connected reverse switch when he swapped tranny. is that it circle in red in pic? i know it supposed to have to wires but not sure where.

more research, i guess that's not it. breather cap. i think i found it now.

That is in fact a breather cap. Look further towards your transmission mount posts and you'll find the threaded hole for the reverse switch.

Should have a green and black wire coming out of it and another wire of another color.

Give us some information on the car? Was this car originally a 5 speed or was it converted (like mine was) from an automatic? I had a lot of reverse light issues since my car was once an automatic.

there is what looks like a bolt on the front, bottom side of the trans. It may be sheathed in rubber, but it will have a plug/wiring connected it. This is the reverse indicator plug.

Yup that's it^

check the wire it's self to see if there are any brakes in it

thanks for the pic. found it on my tranny now. just have to put tranny in reverse and test it. is it resistance or electric power...voltage i should look for?
car is an original us 99 si with a tranny from another 99 si.

B_Swapped93

electric power in this case.

thanks. will pull switch out and clean, test it. see if that is the problem.

If you just want to test the switch itself, set your multimeter to test continuity and hook the probes up to the terminals in the switch and depress the switch itself. You should get continuity.

Jump the harness side reverse light plug, the reverse lights should turn on. To jump the plug use a piece of wire and insert it into one side of the plug then the other end of the wire to the other side of the plug.

This is what it should look like. Make sure not to let it touch any metal.

update: jumped the hardness with wire and reverse came on. took switch out and one of the wire was snapped. soldered back on. put in reverse and lights came on. it's all good now.
thanks a bunch guys. much appreciated!
