I'm building an FD which will have a single turbo, EV14 injectors, wideband, electric air pump, a new fuel pump, and stock ignition which I will upgrade at some point. I plan to go with a bare bones approach for the engine and eliminate as much as I can while still passing Oregon Emissions.

I feel like half the stock wiring harness is going to be either unused or can be removed, and a good chunk of whats left is going to get redone (new fuel pump wiring, new injector clips, WB, air pump, etc). At a certain point, does it just make sense to buy a M2000 and wire it in with as much new clips as possible? I realize this isn't a trivial amount of work but its starting to sound like it isn't a lot more. With all the cutting and splicing, I would think it would be cleaner and easier to add to should I go that route.

What have you guys been doing? Am I underestimating the hell of looming?

If it is your first full harness, it will take you a long time to do. However, if you're redoing much already, it's not really a far cry to just do the whole thing.

You will want to make sure you layout and plan your wires before you cover the entire harness, else you inevitably want to redo something or add a wire here or there.

I have done multiple kit car engine at and body harnesses (for carb'd vehicles), and had years of experience doing mobile audio and security, along with some aviation maintenance experience.... this harness is proving to have its own unique challenges. Most of those are self imposed due to a desire to make things optimal, and having to compromise between oem level standards of today, or autosports/aviation 'standards' that are way overkill for what I will use this vehicle for. I will probably have hundreds of deutsch dtm connectors left over after I made some impulse purchases.

Basically, you can make it as simple or as complex as you would like. The little things like the Adaptronic article on sensor grounding will help with your final result and really doesn't require any more difficulty.

diy loom, just remember how old the car is and the wiring in the engine bay with a lot of rotary heat

Thanks for the input. That's pretty much what I figured the answer would be. I know I'll have my work cut out for me but I'd rather not trust 23 year old wires if I could avoid it and I should be able to clean it up.

Wiring is one of those things I always try and tackle as a DIY project, overplan, spend a ton of time on and more money than planned, and ultimately just wish I'd have bought the harness from the wiring guy who could do it 100% correctly in half the time without any additional headache on me.

I'm a huge DIY supporter, but wiring a full engine harness sounds like a nightmare to me especially when the long lead looms are like $300+ and you can get a rywire for $500 and then use a PnP unit. To each their own though.

^ yup i feel ya.

I had the same realization recently.

I don't have a welder and can't weld so i pay someone to do it. I should have done the same thing with the wiring. I should have bought a pre made harness for my car, installed it and let a shop take of the rest.

I bought high quality sxl white wire on spools and weather pack connectors for everything, it wasn't as expensive or as hard as I thought it would be.

I used clear heat shrink and put numbered and sometimes labeled pieces of paper under it before shrinking so I would know what the wires were. Its been very helpfully when I need to troubleshoot.
Put the number/label at any connector area so its easier to trace.


I would like to redo it someday, it was my first try and the routing is a little messy in a few areas but over all it came out looking clean and it worked.
