The non used greasy, dirty space under the seat became my target for this.
I had to fabricate a "front wall" and a "floor" to make it suitable.
The "floor" was needed to protect from the smudge from the chain and to mount the MAP sensor. The "front wall" to avoid engine heat and road dirt and to mount relays and fusebox.
The ECU found its place on the inside of the OEM plate for fuses and connectors.
Down in the bottom of the cable cave I fitted the fuel pump. The V shaped cross member between the frame rails was after some hard massage a perfect place for the fuel pump.
A very snug, but big enough place.
But more about the fuel pump/fuel system later.
Testfit of the ECU, "floor" and "wall"
Fuel pump wired for test and plumbed ready
to get some hose clamps and get mounted.
The gadgets in their final positions
with the fuel pump in the bottom.
