Yeah, I'm not sure what the "led" looking thing with the two wires is for. You can probably tell by the number of posts I've made on this board that I am by no means an expert on the electrical and mechanical systems of the 4Runner. I'm sure someone out there would be happy to tell us what that thing is though.

I did end up using the little straw that came with the can of QD cleaner just because without it I was spraying that stuff all over the place. I just made sure I was very carefull not to get too close to the wires so I wouldn't bend or break them.

I think you should be able to get them clean without the straw. No need to waist your money on another can just for a straw.
