Default Honda Wiring Concerns

Im a northern michigander who has been a honda enthusiast for a while. I started my first Trail rail project which is a Volkswagen frame, steering, and suspension, but runs on a 97 honda civic d16 motor and 5 speed tranny i built for my civic. This is the first time I've ever tried to run a PGM FI motor outside the vehicle. I scrapped everything minus the main engine harness, the ecu, and i have the PGM FI relay with connector, among many other things(Radiator, FPR, Ect.) from the car. I wanted to wire in an aftermarket fuse box i picked up with only the necessities. I have the OEM Honda service manual with all the diagrams, but as i said am new to making a standalone system. Can anyone help guide me towards a good source for information for pinning out accessories and repinning the necessities.
Any help is appreciated.

I want to delete all my accessories, and hardwire my ignition and fuel pump to switches using the stock ECM and get rid of the rest of the wires i dont need, and cant find any threads or posts online on stripping and rewiring my harness for just the necessities to make my motor run.

It's a very basic fuel injection motor that relies on the distributor, crank phaser, coolant and air temp readings to operate the fuel injection and timing system.

So my advice is to keep everything in the engine harness minus the AC system.

The ecu is triggered by a reference signal from the key so there is no antitheft or trickery involved with ecu power and motor function

So run everything off of the stock ecu, wire in your own trigger for ecu power from a switch. Let the ecu command the main relay and read cam, crank, coolant, air, and exhaust readings and that's my general over view

So basically supply power on a switch to...
Plug-A pin-11 and pin-24 ...
And then ground Plug-D pin-13?
That really is as easy as it gets

How do you plan to shift the transmission? Z linkage?

Manual cable linkage. It lines up almost perfectly with the frame. Weld in a bracket and mount the linkage to that. Probably get one out of a scrap car at a junkyard.

Well the advice helped, thank you very much for the input. I'll be creating a new post or moving this one soon. Everything minus the fuel pump and lights are wired in now! I appreciate you guys! 😁

I'm hoping it'll pull the tires. Not sure where I'm putting the fuel cell yet. Been winging it as far as design goes. I'll be sure to keep updating. I only work on this thing once a week.

It's a cool build for sure. I've always wanted to take a D series and build a go-kart around it. My idea was to use an auto trans to get away from the shift linkage issue, but I'm definitely looking forward to your idea.
