so i bought this car about a month ago and looked up under the dash to notice a couple pink fuses... i think they were fives or something but anyways then i look over and see a wire running off them going to towards the passenger side that has "To Speed Density Switch" written on it. i have no idea what this is and just wondered if any of you might have any ideas as to what its for?I haven't really got a chance to check on where the wire leads too...obviously the speed density switch or whatever but i will check in a few days.. Anything helps! thanks.

 

Oh, the good ole Speed Density Switch. Don't touch it, it controls the Flux Capacitor!

But seriously, it sounds like some custom wiring that the previous owner added. If you have contact with him, I'd ask. If not, you'd need to trace the wires to see where they go. It could be really anything, it's hard to tell.

I know I didn't help much but I still hope it helps.
