Alright, so I bought the car as a project with hopes to get on the road ASAP. It already has the s4 N/A engine mounted. I am fighting with mounting the wheels (aftermarket, onto 5 bolt 2nd gen hubs with T2 brakes and aftermarket 2nd gen suspension), mounting oil cooler, attacking the lights, etc.

The battery is mounted in the trunk, and there are 2 wires coming from the trunk battery into the engine bay. I need to mount some wires to the starter..... what wires go where? I also have to put in the engine wiring harness..... what needs to be plugged in?

Thanks everyone.

 

your BIG wire from the back goes to the starter and the other one goes to your alt. Thats if you have a kill switch which you should if yur battery is in the trunk.

 

Could you explain to me how to set up the "kill switch" please. It seems pretty straight forward, but I just dont want to mess up the wiring. Thanks.

Can anyone give advice on where all these wires from the wiring harness go and what sensors I have to make sure are hooked up?
