Does anyone have a circuit for what is going on inside the big brother box? Would it be possible to completely eliminate it with some modification?

The PO of my car cut some of the wires to the relay and I would like to do it right rather than trusting the hack job currently present.

Thanks

already done man. the two yellow wires are joined....thats all thats needed IMHO

Yup. If you want, you can solder them together and then shrink-wrap them to keep water/dirt out. Or use a crimp-on splice--but then you still want shrink-tubing to keep the water and dirt out.

The other wires don't do anything. Well, sort of... If you just cut them all off, other things in the car may not work correctly. To run a single wire to several different places, VW/Karmann would often run a wire to the one place, and crimp it and another wire into the connector on the end. The other wire would then run to another component. Sometimes yet another wire would be crimped in with this second wire in the next connector. Different components could be "daisy-chained" together this way without running separate wires to each.

The key is, if there are two wires crimped together in any connectors, you can cut the wire and splice those two together. (Crimp or solder, your choice!) Remember, shrink-tubing will help keep the connection clean and dry.

If there is only one wire going to a connector, you can cut it off and insulate the end (tape over it or some such).

The two big fat yellow (or yellow/red) wires do need to be connected.
