Hey all, I am hooking up a remote start/keyless Hornet 570T and I need negatives for the door locks. The door locks are positives. I have a bunch of relays, but they only have wires in 30, 85, 86, and 87a. don't have any way to get more right now. can I use these, if so, how. diagrams I have seen need the regular 87, not 87a

Cut the diode out, and use an additional wire with a 1/4" female quick disconnect for the 87 terminal in the relay harness.

You'll need two relay's, one for lock and one for unlock.

85 + Input from keyless

86 Gnd

30 - Lock/Unlock Output to Doorlocks

87a Not connected

87 GND

When you press the lock/unlock button on the keyfob... Terminal 85 Energizes, and engages the coil which swipes the wiper contact 30 to contact momentarily to pin 87.. Giving you your - pulse door lock outputs...
