Wiring Harness/GPS Gauges/EFI Engine

[Papa]

Randy,

That's a lot of questions all at once! I've done my car with BPE's 347 and EFI, so I can assist with the EFI wiring. I have no experience with the Russ Thompson turn signal setup, so I'll leave that for others to help with. There is no check engine function provided with the EFI computer, so I'll be no help there either.

I assume, please tell me otherwise, that your BPE provided EFI is the Holley Sniper? If so, this is very easy to get wired up.

1. Run the main power (red) and ground (black) wires directly to the battery
2. Connect the pink keyed +12v wire to any +12v keyed source (must have +12v when key is on and when cranking)
3. Connect the blue fuel pump control wire to your fuel pump (+) wire (I did this by de-pinning the fuel pump wire in the dash harness)
4. Connect the fan control (light blue) wire to one of the two green fan wires available (one near the top of the engine and the other at the bottom of the radiator).
5. Connect the coil wire (yellow) from the EFI to the (-) post on the coil
6. Connect your (+) post on the coil to any +12v keyed wire (typically the EFI/COIL (orange) wire in the RF harness)
7. Re wire the inertia switch to be in-line with the fuel pump ground wire (I still need to do this)
8. Install the CTS (if BPE didn't already do it) and connect the CTS plug from the EFI to the sensor





The fuel pump connections can be done as I've described, or in many other ways, including splicing into the fuel pump wiring at the fuse block. You'll need to decide how you want to make these connections, but as long as you have the control wire from the EFI driving the pump, you'll be good to go. I also de-pinned the output plug of the EFI harness down to just the single fan control wire.

I originally had the FAST XFI Street system installed, but BPE replaced it with the Holley after I started having issues. The swap is documented starting at post #618 in my build thread:

Let me know if I can help answer any other questions you have on the EFI install.
