Hi guys,
I was planning to take off the auxiliary fuel pump pressure switch that came with the V2 kit and noticed that the red wire from it was attached to a small black square box (circled in red). The yellow wire wasn't attached to anything as you can see and the black wire went to a ground. What's the little black box all about? It has the name Siemens on it. I didn't see any writeup in the Stillen instructions about it.

 

that is a relay......

 

that would be called a relay

 

a relay.

 

Lol! Thanks guys!
I see now that the relay was listed under the Stillen Auxiliary Fuel Pump Electrical Assembly list. I guess I can just cut the connections to the relay?

 

B.C.,
That's the relay. Yes it's in the write-up (well, my write-up anyway). But why is your yellow wire not connected?

 

No idea! I'd better look up your notes.

 

Which yellow wire are we talking about? The yellow wire on the auxiliary fuel pump pressure switch need not be used. The yellow wire on the auxiliary fuel pump relay should be connected to the OEM relay by the driver side kick panel.

You're right, the Stillen V2 instructions do not mention the installation of the auxiliary fuel pump relay (the V1 instructions do).

 

Yes, since you're using the Walbro. But why cut the wires? Remove the relay and everything associated with the aux fuel pump. This will significantly cut down the wires in the engine bay.

 

The V2 instructions spell it all out on page 13, and a little bit a few pages prior.
