I am in the process of installing CB Performances EFI system.

I have a few questions in regard finding wires from the front of the car to the engine bay.

Fuel pump - Do the two wires that connect to the pump up under the fuel tank, run back to the engine compartment? I need to find a place to tie in the wires form CB's harness instead of running new wires all the way to the front.

Tachometer - Is there a wire that goes to the tach that I can connect to their drop for the tach?

Ignition - There is a drop labeled ignition is there a wire already back in the engine bay or do I need to run this up to the ignition switch?

I ran new power and ground wires to the front when I rebuilt my wiring harness (out of the car).

I also used the stock relay board to connect the new EFI wires to the stock system, and created a new cushion wire harness that uses the stock 12-pin plug. That connects to the fuel pump power, ignition, and tach.

BTW, the Dubshop EFI kit includes a tach signal modifier box.
