Made up a junction block for the 4.8 v excitation wires from the EIS to the fuel pressure sender and fuel level senders. I will add a resistor for the amp hall effect sensor later if it is needed.
I used an 8 section strip divided into 4 parts of 2 sections each. Each part has a 4.8v input jumper from the EIS, a resistor of the appropriate value, and a place to connect the appropriate aux wire from the EIS and to the destination (fuel sender, level sender or amp sender).
Installed the end fitting on the orange wire and attached it to the sensor. Spliced the orange EIS wire to the new orange wire extension that attached to the sensor.
Installed an adel clamp on the wire bundle on the port side of the wiring run, attaching the adel clamp around the wires to the adel clamp attached to the engine mount.
Installed a hard plastic grommet in the hole through the firewall for the MAP line, and secured it with red RTV. Drilled a hole in the side of the "well" near the MAP unit and installed a plastic grommet. Ran the MAP tubing into the firewall, though the side of the well, and attached it to the MAP box barb.
