Hi Clay,
I’m getting ready to do an EFI install and your suggestion of wiring the engine on a stand, then take the harness off to do the install makes a lot of sense to avoid fighting it in tight spaces.
Tell me how you might modify/improve on the following approach:
1). With engine out, drill an access hole through the back panel below the passenger side rear seat, mount the box under the passenger seat and route the loom through into the engine bay, temporarily secure the wires so they lay down cleanly.
2). Mount relays, O2 controller, ignition components and any other bits not mounted on the engine.
3). Plan roughly how the loom will be safely run in the engine compartment and temporarily secure the loom to the car. Adjust as needed to safely avoid moving parts, high current or voltage components, then establish a fixed reference point on the chassis next to the loom and make a corresponding mark on the loom, to give an idea of where you want the engine mounted loom to arrive at when the engine gets back into the car.
4). Plan loom routing to previously set components in the bay and on the engine.
5). Remove loom and box from car, locate reference mark on loom, add 12 inches, (or what ever additional length you feel comfortable with), then establish where the chassis mark is to give yourself a solid starting point to route wires to the components and install their connectors. There is a similarity here to wiring a house - set the boxes where you want the receptacles, switches and electrical components and run your wire from the boxes to the panel, securing the wire as you go, then trimming the wire, once run and finally, make up the boxes.
6). Remove the newly trimmed and terminated harness from the engine and install it in the car, then install the engine and hook up all connectors and computer.

7). Alternatively, would it be possible/preferable to leave the loom connected to the engine, do the engine install, pulling the harness, (loom), and feed it from engine bay to the interior for final hook up.

At what point do you want to hook up the brain box and start verifying connections?
I’m starting to locate components for fuel and EDIS and getting them mounted

Thanks,
chris
