Thread: Disco tank into County

bee utey, good morning,
I have a stand alone system from a 93 Disco . Don't I need the speed sensor as well wired in , originally on the Disco this plugged in not directly to the EFI harness so I don't know what to do with it / where to tap it into the EFI harness. Do you wire in the fuel cut-off switch ? I read somewhere that there is an inhibitor switch wiring , and with a manual trans this has a certain resitance installed and then grounded ? I think its the orange wire hanging out of the end of the harness before the main 9 pin plug , would the reistance already be in the harness or would it be in the main body harness somewhere ?
Questions Questions , Cheers

Here you are. I've labeled them with figure numbers for easy reference.

Figure 6: Oxygen Sensor behind the Y in the exaust. Not sure if this is for the petrol fuel injection system or the fancy new gas controller that Bee-uety installed at the same time.

Figure 8: The ECU in the battery compartment (other side of the above) all covered in some Martian terrain. Note: everything connected by ribbed tube is unrelated. The small, smooth tube going off to the right goes down the passenger side of the chassis to… the fuel gauge sensor and/or fuel pump?

Let me know if you need photos of anything else or same components from another angle. If you want to zoom in closer, you can grab the high-res images and a few more angles from here https://www.dropbox.com/sh/m1a3bbh8m...QZw-Xq8nfPmoYa

If I remember correctly, the fuel pump runs the whole time, even when on gas. Apparently this is possible because the early fuel injection systems are too simply to know that you've shut off power to the injectors. This makes change-over between gas and petrol super fast. Barely misses a beat, even if I do it going up hill. It does however also mean that if I ever run completely out of petrol, I'll need to pull the fuel pump fuse out in order to save the petrol pump from expiring itself.

For anyone considering this modification for a V8 over the original carbi setup, I can recommend it highly. If you are in SA, Bee-utey is the man to see.
