need help with nelson harness... a buddy is installing the harness for me and called with a question..
he says on one of the relays there are two terminals, one labeled L87, and one labeled 87. says on terminal 87, there is a slip on connector, he calls it a spade connector, but there is no wire coming out of it. he says that terminal L87 has a wire coming out that goes to the fusebox.
what is supposed to be hooked up to terminal 87, if anything? any ideas?
on the other relay, both terminals, L87 and 87, have wires coming out.
thanks

It's a Bosch type relay, 30 is power in 87 and 87 A are normally open / normally closed, which means one turns on the circuit when the relay is energized, one turns off. I forget the numbers, but the one in the middle is N.C. and the outer one is N.O. (like to turn on a fuel pump). Most relays have a schematic on the side. the one that is touching 30 is normally closed. (On when relay is off...uh...I confuse myself sometimes...)
