Im working on a keyless ignition for a sportster.

I have figured out how to make the system work using 3 spdt relays.

Space is my issue. Between the controller, the relays, and my keyed ignition cylinder(have to keep it for current resistance), and all the wireing. I dont have the room to hide it in the space i have.

Is there a relay i can buy, that will latch on with channel A negitive pulse, and then unlatch/reset with channel B negative pulse? My current draw is a maximum of .04amps, just has to be able to take some vibrations, it is on a harley after all.

Thanks

The last listing above is a relay GM uses in many of their newer vehicles. Ebay search of a Corvette fusebox will get you that relay, plus a few others, fuses too. All for less than the GM retail price.

Thank you, after a little more seaching, I found a 4-channel 12v relay module 1/3 of the size of all my relays and much cleaner wiring.

Can you please give a link to the above relay, also look for Omron dual coil latching relays.

Can you please show us a diagram for your keyless IGN?
