i need some wiring guru's help

first of all ...i've learned alot here in the org and i don't even have a maxima


im about to install a vq30de into my s13 and im not using a/c,p/s or any other stuff like EGR,EVAP well not even IACV ,so my question is ..to eliminate all of the unused wires on my engine harness ,i have spliced the entire vq30 harness and see that some of them are going to the same place in the case of sensors that need 12v+ or ground ...can i just cut the wires i don't need


i'm sorry if my english is not that good but my first language is spanish and i'm in mexico

 

I would think you can remove power from those acc you're not using..

btw.. how you get a 240 in mexico?

 

As long as you dont cut the wires going to the other sensors, you are find to remove the 12v wires. I would leave the grounds and place them in various parts of the engine bay

 

You should be fine to cut any wires leading to a component of one of the aforementioned systems (a/c, p/s, EGR, EVAP, IACV) Just make sure not to cut any of the important wires (MAF, TPS, crank POS, crank REF, cam POS, injectors, coils, O2 sensors, Absolute pressure, ECTS, KS, fuel pump, etc.) Also, tape up or shrink wrap the ends of the unused wires so the can't make contact with anything. You are going to have a bunch of codes, so maybe don't hook up the MIL either.

 

thanks ...i got a 240sx in mexico because i live on tijuana(just across the border from san diego) and you can get them imported for like 800 bucks and afterthat you can do whatever you want with it ..as is no emissions and you can do any swap you want(v8,turbo,jdm engines) you only pay a 100 bucks a year for registration

 

ok now i have another question ...what about the pins that go to the ECU plug??can i just push them out of the plug???

sorry if i sound noob thanks in advance

 

well here's some pics of what i've been doing with mi wiring for anyone that cares hehe

it started with this


to this



i just got a question..is the map/baro(boost sensor really necessary)i see tha it gets 5v+ from the same place as the tps but i want to know if it is only for emissions ,and the wiring diagram from jwt does not even mentions it



her are some pics of my soon to be installed vq30

 

nice lookin' engine..

 

thanks,i hope to installed in the next couple of weeks

vq30+z33 6 speed+s13=win hahaha

 

Yeah, if you want, just push out the unused contacts from the plug. Just be sure to release the locking mechanism first. And then you'll have to release the tab on each contact.

Tyco Impul-Lock Connector Instructions.

As for the Map/Baro sensor, from the FSM:

"The absolute pressure sensor is not directly used to control the engine system. It is used only for on broad diagnosis."

 

What intake manifold are you using? I'd use the 00vi if possible.

 

thanks for the tip ajm8127,im goin to post a pic when i finish my wiring now with out a map/baro sensor(i could'nt find it on the FSM or i just suck at searching througth the FSM)..

as for intake manifold ...i can't use any FWD designed IM so its going to be a custom manifold with Pathfinder TB .

 

I see, good luck with the swap. I look forward to see some track times.

 

Map/Baro sensor info is on page EC-110 of the '97 FSM at least. It's under a section titled "Absolute Pressure Sensor".

 

I love the VQ.. however i love the lsx's even more.. s13+ls3/7/9= super win!

 

i would like an ls swap but that is going to be more expensive,i think i could boost the vq30 for less than 3k(including engine,tranny,turbo and other stuff) except an ECU tune

 

well i have another question..if someone can help me, i got the wiring almost figured out just need someone to confirm some wires for my s13

ECU back up power----pin 80
ECU relay ----pin 24
ECU power ----pin 67,72
fuel pump signal ----pin 11

 

Sorry I can't help you but beautiful motor dude!

 

thanks i'll do an update to my build thread soon ....stay tuned hahaha

 

Pin 24 runs directly to the ignition switch from what I can tell. Pin 4 is the coil (signal) to the ECCS relay. Other than that, it looks good.

 

ok thanks ajm8127
