Wire Tuck Question

[ace79]

Yeah, I got them too. Thanks anyway for extending your hand to help out!

sure ah? This one has the VTEC supplement, unlike some of them that don't.
So it includes some of the wiring diagrams for a B16A engine.

Sure ah, are they the same?

The inside interior, you can check the normal D-series EG manual.. they're the same as stock, only the engine area harness is different.

Yeah, I thought about that too. But I actually want to make a whole, brand new set of engine bay wiring. But then, to me, it's a good idea for a electrical noobie like me to have an actual wiring set, and copy that to my own harness. Then , when it's done, only then will I remove the wiring in the engine bay and fit my own harness which will be hidden, or "tucked".

From what you say, I think it'd be cheaper and easier to simply buy another EG harness, and mod the one in your engine based on the harness you bought. It's also a backup in case you 'screw' up.

Now this is quite interesting too. Any ways for you to send me a colour copy?

If you want photoes of how americans do it, I have a mag that illustrates it, but even to me, that kind of mod is really too extreme and risky.

Ooohhhh, in this case, I intend to buy those nifty wire/cable labels, the ones with numbers made from plastic wan....heheh. Anyway, I will wrap up wires with a water resistant loom, maybe fit the wire labels ( maybe laminated? ), since I intend to use just one single colour.

As for cataloging and labelling wires.. forget it, you best keep it in on paper or something. All honda wires are properly colour coded, so once you list them out, I think you can find them easily. Anything that's paper material in the engine usually disintegrates under heat and water.

Or, is it safer for me to just buy a spare B16A OBD1 harness, and mod THAT instead? But is it still possible for me to use those nifty waterproof Molex connectors, when I'm re-using OEM harness? Now after re-reading your reply, it seems like it is much safer for me to just re-use and mod one ori engine bay wire loom instead.

If I choose this route, which wires should I buy? AWG 18 or 20, or 22? I understand that it's safer to weld up higher rated wires to be on the safe side, rather than welding up lower rated wires ( lower than the current wire's AWG rating ). Now I do not know what's the AWG rating for B16A OBD1 wire, is the whole hog of wires is of the same AWG, or do they have diff ratings?

Looks like when the funds is green to go, I should buy a set of wire crimpers and plenty of wires to practise 1st! :regular_smile:

Yes, they are.. I checked when I was doing rewiring for the JDM foldable P/W and my CD player. Same for the interior, as I already checked again for the wiring for my radio when I was wiring this harness (because I do not like butchering the original harness, and troubleshooting that mess of wires is a time-consuming job I simply don't have the time for.

One thing you have to remember, the 02 sensor, map sensor and the TPS works by detecting resistance (or the lack of it) (in a roundabout way, since the output is in voltage.) I think slight changes in resistance wouldn't mess up the readings, but there's a reason why when you replace the TPS, you have to calibrate it. Wires affect resistance so when you make your own, those minor differences in wire gauges, length might just add up to make a substanstial difference. (sorry, I quit EE before finishing it, so my knowlegde of electronics are rather lacking.)

Now this is quite interesting too. Any ways for you to send me a colour copy?

Sure.. pm me your mail add, and I'll scan it for you.. I think it's like 4-6pages?

Or you could buy the mag. It's in 'HCi' January 2007 issue. A K-series wire tuck, detailing the procedures and equipment.

Oi! you think this is a computer networking project ah? :P (just kidding)
Seriously, a single colour is a bad idea, because you cannot double check what you do.. (trust me on this, I've done a bit of wiring work myself, although not on cars.)

Sounds like a good idea, but I think you should see the wiring tuck article before you decide anything. I think a spare set of harness is a good idea, because unless if you're doing this for a living (i.e. you've done this lots of times), you'd inevitably screw up. But wiring tuck is always done on a original set of wires, not a fully custom one (although K-series swap craze has americans making full custom ones now for the EF/EG/EK, and they're not exactly cheap, if you're even wondering.. :P)

Wait.. Molex connectors? Are you kidding me? Those connectors are not even vibration proof! They'd loose connection or get shaken loose, if you're thinking of using them.

There is a reason why the original harness connectors have tabs and crazy shapes molded into them. They' have to be heat-proof, water-proof and vibration proof!

I understand that it's safer to weld up higher rated wires to be on the safe side, rather than welding up lower rated wires ( lower than the current wire's AWG rating ). Now I do not know what's the AWG rating for B16A OBD1 wire, is the whole hog of wires is of the same AWG, or do they have diff ratings?

Dunno, I never butchered my own wires to find out. as for higher rating wires and what it affects, read above, second answer.

Looks like when the funds is green to go, I should buy a set of wire crimpers and plenty of wires to practise 1st! :regular_smile:

One thing I've learnt about wiring work when I was doing my EE course (fresh out of school that time) is that crimping is a compromise. Soldering and proper insulation is best.

Actually I have the stuff like wire looms and stuff.. but chickened out on doing it.. I'll try post some pics, but take time oh!!

And the wire loom in the picture was bought from a computer store.. I've since learnt that there is another version sold at jalan pasar for heavy duty equipment, and they're thicker and only available in black. It's the same one that appears in the magazine article I've told you about above.

But I'm abandoning the wire tuck project for now due to complexity.

Good luck on yours.

Edit

The only wires are different in the engine and dashboard harness is the additional VTEC and VTM wires, plus a few other wires that I don't remember.

Photoes will come later.

Radio harness, because I don't like removing the stock connectors for whatever reason. I waited quite a while to get this so I can actually install a CD player in my car.. LOL!

My magazine collection..which I dug up to find that article I was talking about. I spend enough money on this to buy maybe one or two carbon fibre racecraft lips.. :P.. Crazy, but I've realised that sooner or later, we have to look to the US for old school honda parts.. Japan is 'probably' very close to running out of them or stopping production already. So JDM or no JDM, we might not have a choice in the matter anymore.

The wiring kit I always have around when I was doing rewiring for the rear bonnet area (previous owner modded the car as an audio show car, evident by the cut wires, holes and etc. UGH!) The looms are just leftovers from my computer PSU wire looming thing done maybe two years back.

Whoa, info overload! Ok, looks like having a B16A OBD1 harness in hand, rather than building up my own is a better option. Well, looks like more reading is required, thanks!

And I think I got that HCI Jan 2007 too. Mags, sheesh, don't tell me about it! I spend RM 200 monthly or more for cars and bikes - related mags! And since 2002 too, so go figure!

ace, tat's why la, u should have buy more car stuffs.....but wat to do, my mags collection cost more than a CF j's racing bonet alrdy......sad.....

Lol.. we should 'pakat' to make a hondarian library one day.. :P

 

[xxxx]

haha.....not a bad idea........

 

[ace79]

Well, try not to calculate how much we spent on mags, or else, you will be thinking : Oh, I can buy this for my car, buy that etc. To me, the mags I buy inspires me, gives me some knowledge ( like how to loop your power steering rack etc ) and ogle at those yummy cars and bikes that I can never afford.

Oh well, now back to more reading and reading up threads on wire tuck in general.
