Help.... Yellow wire w/ black stripe, 1972 El Camino
 

I'm working on a 1972 El Camino that I recently purchased.
I have a thin "YELLOW WIRE W/BLACK STRIPE" under the rear rug and I don't know where it goes.
I had sold my 1971 El Camino years ago and my repair book w/ diagram went with it...
It's probably the same from 1968 to 1972.... Thanks

Google 1971 El Camino wiring diagram and it should come up. I've done that
on a number of occasions and got the info I needed. Hope this helps.

Oops meant to say 1972. Probably the same as 1971.
