nova immobiliser

[torquey]

Need some help with wiring a cat 2 immoboliser into a c20let loom its fitted to a nova. There is a black wire coming from it which goes to which colour on the let loom ???

[Lee H]

I've always wired immobilisers into the car loom and not touched the engine loom. Also if it's a Cat 2 immobiliser it should have lots of black wires to connect up?

[mowgli]

you sort of need to advise make & model of immob. before anyone can help. they usually kill off several feeds & not just one

[Graeme]

Personally I'd break the black with red trace to starter, red with blue trace to fuel pump and black to ecu, any good immobiliser should have three points

Ok cheers its a sterling one its seems to b working but iam left with two black wires

[mowgli]

working as in

1. the car is running

or

2. the car isn't running

??

Usually connections as follow

Permanent live
Switched live
Earth
2 immobiliser circuits (4 wires)

[Jon_nova1]

You need to tell us what the black wire is for? as you sure its not got two and its the immobilier circuit?

As Lee says, should have lots of black wires, usually with the ends with differet colour bands on them

[torquey]

The car works but need to know where these two black wires go as it was wired up into the old loom before I removed it also need to know which black wire in the let loom I should tap into

Right I've had another look there are 4 black wires 3 are wired inn iam left with a black with brown flecks on it so where should it go in the c20let loom ???
