relay diagram for alarm

Hello,

I am installing a car alarm and  i'm having trouble understanding the relay for starter kill, here is the wiring diagram.

Its the relay in the red box. The numbers look nothing like the relay supllied. The supplied relay is 5 pin 30,85,86,87,87a. Can anyone make sense of what it is asking me to do? I have very basic knowledge of relays.

Thank you

sorry hope this is clearer

Thats not a starter kill - that is an ignition kill. Same principal, but they are showing you cutting power to the coil, thus preventing ignition. The more acceptable approach is to interrupt the starter wire coming from the keyswitch to the starter solenoid. Make sure you connect the + side of the relay to switched ignition NOT constant 12vdc.Kevin Pierson

Thank you for your reply, sorry but my relay knowledge is limited what numbers do I connect each wire to.

Thank you

so would the starter go to 30 and 87a with arming out to 85. Is that it or relay need ground too?

Thanks

Yes, your pin numbers are correct. I would assume the "arming output" is the ground, connect it to 85. 86 will connect to switched ignition. 30 and 87A will be your starter wires.Kevin Pierson

One look at that diagram says bin it, it's a POS. It's also telling you to cut the ignition which is a real no-no. It should be the starter, this is the correct diagram relay_starter_cut.bmp

Sorry Kevin, didn't see your post, that unit's a Fleabay Chinese piece of junk. Can you even see how it gets it's tach sense? Please don't say oil pressure switch.

Thank you very much for your help, i now have the confidence to go ahead.

It has no tach sense or anything else to compensate. The remote start will not used anyway. It has no use whatsoever in the south east of England where the temperature is rarely below freezing or above 80oc.

Thanks again.

Also I would never have used the ignition wire. If the relay had failed while driving my car would've been a mess.
