Second ign, 3rd accessory, relay wiring

Hi everybody

Im always reading that you need to power up the second ign or second starter etc.But know one ever shows how to do the relay.

I've heard you can just jump the wires,but people have if you have a problem you won't beable to tell whitch wire it is.

Can someone please post a Diagram of how the relay should be wired up

Thanks

Thanks alot

so the orignal starter wire would just go to starter and then you would branch it off with a realy

ALso,when doing dome light supervision or whatever its called.Do i need to use a realy or just  hook the wire from the rS/alarm right on to the dome light wire.

It depends on the rs you are using the problem with branching off is that the relay would energize with the key also.Alot of your rs have a neg stater,acc and ign output to turn on these relays. So if they have these neg outputs you would wire 85 to neg out put for start, acc, or ign which ever is needed then 86 to 12volt  30 12volt  87 to the cars ign, acc, or stater wire that you want to power.

O i see,so its like going backyards

if thats correct i fully understand then

well i would problem be using DEI and Autopage as those rwo brands i like

See i keep thinking about the 300c etc that have a NEG 2end starter wire well the main is (+)

So thats why i wondered how you energize the starter wire etc
