fuse box relocation

[Options13]

so i'm in the middle of a fuse box relocation in my s13, i cut the harness to shorten it to find out that there are same wires with the same colors?!

what do i do in this situation..?!

in the pics you can see some of the ones that are the same color.. there are alot of pink.

hahahahahahahahahahahahahahahahahahahahahahahaha

you should have marked them before just cutting things.

now your best option is to either buy a complete new harness, and do it the right way next time, or borrow a new harness, and trace it from end to end, and then compare to your cut up one.

god damnit, i need to look up the wiring diagram in the FSM and see if i'm even using any of these wires, i'm sure i am though, theres quite a bit of the same color wire, which makes no god damn sense to me..

[Dboyizmlg]

lol, yes you should have marked them with tape... Lol

[Dboyizmlg]

I'll give you a tip.

Some of them, for example: if there are a lot of black ones that are same gauge size, the will have black with strip, blk with one dot, blk with two dot, blk with solid line.

This might help you figure out which ones go where.

[Options13]

Dboy I tried looking for different patterns but the wires are literally identical lol

My sides are in orbit.

[Zenki Kat]

My goodness... haha

[jedi03]

I often us a power probe an see what turns on!

[jr_ss]

SMH... Live and learn I guess. A lot of the same colored wires are used for the same circuits. I.E. Headlights, turn signals, side markers, etc. It's always best to deloom the harness and mark one wire at a time. Good thing there are plenty of S13's being parted.

[hobbs]

Pretty impressive stuff, I've seen some pretty dumb stuff but this takes the cake. Well done!

Step 1 = Remove harness from the car

Step 2 = Take harness and find the closest mirror

Step 3 = Look at yourself while holding harness with dominant hand

Step 4 = Yell "STUPID, STUPID, STUPID, STUPID, ETC" as you hit yourself with your now hacked and worthless harness.

Step 5 = Throw harness away

Step 6 = Buy new harness and leave it alone

LMAO! Hahaha

Funny, but the truth.
We have all made mistakes in life, let this be of a learning experience to OP.

[smoked240]

Oh lord! Why did you cut it? The relay/fuse boxes will fit through the body with some disassembly and force. Good luck with that

[tauntdevil]

In all seriousness, buy yourself a test light and volt meter.

Finish the rest of the wires and leave the same color ones on their own.
Once done, go back to the same color wires and provide power to the fuse box and then, if you have clips, perfect, I have some with fuses in them. If not, just connect them and see what they turn on. Of course, this is after checking the diagram to make sure they dont go to the ecu. Usually same color wires go to the same circuit as jr ss stated. Usually you can get away with wiring them up anyhow, and they still will work the same (normally, not always).

Thats what I would do. But do, next time, label the wires.

PM me and I can help you figure out where they go if you still need help.

well the thing is the harness needed to be cut regardless.. it's being relocated to inside, so it had to be shortened up quite a bit... out of all the DIY fuse box relocation threads it said nothing about same color wires in the harness..

anyway, i had a close look at the wires.. you can distinguish the difference in the by the number of dots, and the boldness of the line. All wires are accounted for except all the pink and orange wires, which i believe are to the headlights and turn signals.

At this point its a test and try. what ever doesn't work i'll just hardwire in.

also do you guys know what plugs these are?

[smoked240]

Yeah I'm relocating mine to hatch unless I can fit it all under my dash. I don't want to cut mine. That white plug In the bottom pic should be wiper motor but I would test fit the plug

[nolandavid]

Lol I feel for this guy. I've done some dumb stuff to but people got to learn the hard way.

[brndck]

usually, when you find a large number of wires that are all the same color, they're either supply power, or ground. grounds are usually black on nissan. i would still recommend tracing all of those from end to end, but i'd be willing to bet that they just supply 12v to whatever is at the other end.

[Fries]

Should have unwrapped the harness a bit prior to just cutting it in half. I'd suggest buying a new harness since you 99.9% have no chance of figuring out what goes where.

Live and learn.

[dbeiler]

Jeez! There is no need for a new harness and no need to turn on power. Buy a multimeter, learn how to read and understand the wiring diagram, and trace your wires to the closest connectors. Any half-decent electrician can have those remaining unmarked wires labeled in a matter of minutes. Without ever even opening the wire harness.

I recommend using heat-shrinkable butt splices. If you're going the cheap route and using solder with electrical tape/heat shrink, the least you can do is stagger the splices. After a little bit of vibration, those lumpy solder joints and protruding wires will poke right through the electrical tape/heat-shrink. Staggering the splices will keep improperly insulated splices from contacting each other. Tracking down a short located in a whole bundle of adjacent splices would be an absolute nightmare.

^^^ thank you, everyone on here is quick to jump to conclusions, ALL WIRES ARE ACCOUNTED FOR EXCEPT.

4 pink wires (exact same)
3 orange wires (exact same)
2 cyan/black strip (exact same)
2 green/yellow strip (exact)
2 green/blue strip (exact)

half of zilvia is useless, thanks to those who actually helped.

I thought solder was preferred over butt joints?

[az_240]

^It's all personal preference. Each has its positives and negatives. I prefer the solder route. Carefully mash down any sharp points with a needle nose pliers and use 2 heat shrink sleeves if you're worried about it. Staggering the connections is also a good idea so you don't end up with a giant lump in your harness when all is said and done.

There is a difference in butt splices...
Standard crimp splices are shit.
Hear shrink solder butt connectors are awesome. I don't remember exactly but it's like
Crimp wires
Heat connector (the ends seal to the wire)
Solder ball in the middle melts and fuses the two wires internally

I still feel solder and standard heat shrink is superior as it is less bulky, get a few of those connectors stacked in a loom and it gets thick quick. Although same could be said for those who blob solder

[crewchief05]

that sucks! should have marked as said. hard lesson there!

That photo makes my head hurt. Wiring has got to be one of my least favorite issues to deal with. Glad to see there is some sound advice in this thread. Good luck OP!

[Silviasurfer]

Some on the same side u may get away with checking for continuity eg. Common ground and ignition etc. but that may just be a few ... I did a few of these in a s14 and 2 s15's all I did one wire at a time .... Hope u get a new harness and u get true any help u need other than that let me know .... Mike

[rawgarage]

Just Buy a harness from me...
