Because of this the footwell wire should have it's own inline fuse.

You can hook wire 5 to any trigger you like but do not use wire 7 for the ECU. Wire 7 isn't isolated by the relay and doesn't protect your ECU. Do not hook up any additional wires to the same terminal as the wire to your ECU.

When you say the footwell wire is a passthrough, does it connect to any terminal of the relay? My relay looks exactly the same and has 4 terminals, 2 for the coil and 2 for the Normally open contact.
Relay terminal wiring is as follows:
Coil1 = brown wire (switched live) - also connects to ballast.
Coil2 = white wire (to earth)
NO contact1 = Red wire (permanent live)
NO contact2 = grey wire (to ballast)

I'll draw a diagram if I get a chance, but basically I want to be able to trigger the angel eyes from the remote (using a interior light cable in the footwell) and also when the side lights are on (from the side light circuit behind the headlight).
I was thinking initially I could wire both trigger wires to the 'Coil1' terminal but my problem is if the side light circuit was live it would probably also trigger the interior lights to come on since they are connected to the same terminal on the relay - hence the question.

I should clarify what I said earlier. By passthrough I mean when the relay is off the footwell wire connection passes through to the ballast and directly supplies the ballast with power. When the relay is on the footwell wire is disconnected from the ballast and the relay supplies power to the ballasts through wire 3. This is why the footwell doesn't light up when the ECU is on.

I was thinking initially I could wire both trigger wires to the 'Coil1' terminal but my problem is if the side light circuit was live it would probably also trigger the interior lights to come on since they are connected to the same terminal on the relay - hence the question.

Your analysis is correct. If you hooked it up this way both your side lights and your footwell lights would go on when the ECU has power assuming it doesn't blow the fuse in the first place. Bottom line is unless you have a relay with the fith terminal for passthrough it's not going to work. Even if you have such a relay you couldn't have both the side lights and footwell trigger, you would have to chose one or the other.

Here is a diagram of the relay kit I have currently:



If the brown is actually meant to be a switched live then this doesn't really make sense as when the brown is live, there will be live going to the ballast on both terminals. It would make more sense if the white cable (earth) going to the relay was connected to the -ve terminal on the ballast but this is not how the relay kit has been wired when I got it. The brown cable is connected both to the relay and the -ve connector for the ballast.

Is there a schematic available of the relay kit iop9000 posted?
