relay question
Ok I'm about ready to start doing the headlight and window relay upgrades. I think I have the wiring figured out except for the 87A. Do you leave it unhooked?

Re: relay question
Assuming your relays are numbered the same way the one I am looking at(pulled from a Ford at a pull-a-part), 30 is hot in, 87A is normally closed, 87 is normally open, 85 and 86 are the coil - one to your on-off switch and one to ground or hot depending on how your switch is wired.
For what you are wanting, 87 goes to the headlights and 87A is left open. |
