Early 911 Horn relay
Can anyone help? I ordered a replacement relay from Pelican and this is what came (I borrowed the Stoddard pic but its the same relay). Besides just not looking right, it doesn't have the right number of spades. My relay is by the battery, and is believed to be original with 5 spades.
![]() It seems the original relay - p/n 901-615-102-00 has been superseded by 911-615-103-01, which from numerous sources looks like the new one above. So, my question is - how do I run the existing wires to the new one, starting at 12 o'clock and going around? Again, 5 wires now going onto only 4 spades. Fwiw I note the bottom 6 o'clock spade is brass/copper, the other 3 are silver. Thanks in advance, ![]() |

There should be a pin diagram on the side of the new relay
Fat red wire to 87 Brown white wire to 85 Small red wire to 86 Black/yellow wires to 30/51 - you can put both onto the same terminal with an adaptor |

In order to be in accordance with the wiring code:
Fat red wire to 30 Small red wire to 86 Brown white wire to 85 Black yellow wires to 87 In your early relay the 87 has two spades, you can make a jumper cable with two male spades to connect the black yellow cables. Also terminal 87a is not existing in your relays, it is of no use for this application. ![]() |
