Hi,

I'm an electric rookie so have to ask some silly questions.
Bought a remote controlled relais, but where should it be connected to? The Relais handles up to 150A, but I don't want to disconnect starter motor. I thought the coil should be dead until the relais switch it for going.
Some pics show my equipment, about 50 bucks for all.

Question, where exact connect to 12V (should be hot all the time, because the switch must be supported without running engine?). Where connect the other lines to the coil, so the coil will be interrupted until the relais switch it to live?

If built in, the remote control make it easy to secure my truck...

Thank you for any input

The single black is the antenna, red and black should deliver currency, where do I get it when engine isn't running.
And which pin of the coil connect to where of the 3 pins of the relais?

 

Well, I think you'd want the yellow that comes off the hot side of the starter solenoid and feeds the ignition. Good luck with it!

 

The remote control will be on the Terminal 86 to a constant hot. Terminal 85 is a ground.

The load's power (like auxiliary lights) should be connected to Terminal 87 or 87a. Terminal 30 is always hot and needs to be protected with a fuse.

I would connect it to the starter (wire that operates the solenoid) as without a tell tale light you wouldn't know if the truck is broken if it doesn't fire or if it's the relay.
That could apply to the starter as well but hey ho, such is life.
You could also fit a wire from 87a to the horn so that when you switch on the ignition without having used the remote you will power the horn. Instant alarm !
