Engine in

[Ashtonr]

Ok got some bike carbs now and I have also grafted most of the Sierra wiring loom in but I have a few sensors which I'm not realy sure what to do with, I have attached a photo of my inlet manifold to detail some of the sensors below
1. TempGuage sender I need this one
2. Air temp Sensor think I need this for the Eletric ignition module to work correctly ?
3. Manifold Temp Sensor do I need it
4 I have a single black wire coming off what I think is the choke see attached picture do I need this ?
5 I have another sensor with 4 wires coming out of the housing with the thermostat in it. I think its the Fan switch but I cant positivly identify any ideas ?
6. Vacuum Vale this goes into the EFI module do I need it ?
7. Vacuum pipe from EFI Module guess I need this to be fed off my new inlet manifold for advance ?

Any suggestions most welcome
