Headlight Mod + other wiring

[MIDNIGHT RIDER]

There are two common variations of the "ice-cube" Bosch/TYCO-type standard pattern 5-terminal relay; an 87A that has the 87A terminal HOT when the relay is OFF and turns OFF 87A and ON 87 when the relay is energized; and, less common, but not rare at all, an identical relay that has TWO 87 terminals and no 87A; the two 87 terminals are ON when the relay is energized and OFF when not.

I may have my 87A and 87 backwards, but you get the idea.

There are even available the same terminal-pattern relays that are both 87s are HOT until the relay is energized.


Parts Express is THE place to buy relays and pig-tails.

I also bought some big bags of 10/12-AWG relay pig-tail terminals and, on anything serious, I remove the 14-AWG HOT and WARM wires and replace them with either 12-AWG or 10-AWG.

No, you are correct: 87 is normally-off, 87a is normally-on.

I cant seem to find the SPST dual 87 relays on partsexpress but i can vouch for them as well, bought some goodies from them before...good stuff.
