I have a 92 4runner and for a while now i couldnt figure out why my running lights turn on when i press my brake..could it be a relay?
oh and from time to time my speedo goes nuts dropping to zero and back up again..
any ideas?

 

see if you have the right bulb in the back tails. it should be a dual filament bulb if its single it can cross the marker lights with the brake lights

 

does it have a trailer harness some times them adapter things go out and cause all sorts of weird stuff

 

alright i'll try checking that, thank!
umm no, no more towing or trailer set up

 

right on, thanks blake i somehow put a single filament bulb in and i switched it to a dual and it works just fine now
now on to the speedo going crazy haha
anyways, thanks guys for your help!
