While replacing my speakers(see thread) when I pulled the speaker panels out,I noticed I had the solenoids for a electric tonneau cover release.They appear to activate the latch the same as the manual/hand pulls.But if I am assuming correctly,mine are not wired because I have a motorized trunk lid pull down. And it seems that where my switch is located in the console this would have been the tonneau switch if it was working?I have an 87 repair and electrical
wiring manual but I don't recall seeing this circuit.
