180sx Type X (Kouki S13 Blacktop) Wiring

[got2b240]

I have recieved a blacktop longblock from osaka in mint condition with a harness and ignitor and mafs.

They never sent me the ecu so I had to go out and buy one for $325 cause I cannot get them to send me one. Anyways.

Turns out that the harness that came with the motor is different than a regular S13. These wires run differently on the ECU plug. So I had to try and figure out some of the positions and switch some of the wires/pins on the ecu plug to get it to start.

I am wondering if anyone can provide me with a wire color corresponding with its role on the plug from a Type-X SR20DET Harness ECU plug?

I need this in order to mix and match the wires to get this motor to run like its meant to.

Anyone have that pinout for the Type-X SR20DET Harness that includes the wire colors and their designated role?

Yes I have done about 3 hours of searching websites and nothing found.

I would jjust have the ecu/harness have it sent for identification/rewiring instead

sorry can't help, type x motor are rare

how do you know it's a type x by the way? maybe osaka is bull ****ting you

[slow s13]

i thought type x had ignitor built into the ecu, is yours a j4?

S15's dont have an igniter, S14's and S13's do. The igniter isnt built into the ECU, its built into the coilpacks.

There are only like 3 wires that are different on the Kouki ECU, ask heavy throttle if they will tell you which ones to repin. They know, they just might keep that info secret. I might be able to tell you in a little while, my buddy just ordered an S13 kouki engine/harness/ecu.

[got2b240]

my ecu is a E5 and i am using a different harness than that of which is compatible with the regular E series (E5, E6, E63, E62).

The ignitor wires are different from what I see so far, but I know there are other things, and thats why my car idles and drives a little supratically. I already did timing, tps, and all of that stuff.

[got2b240]

if you can please tell me what the wire colors on that harness stand for (pinout/color code) that would be awsome

[SpeedRacer1]

Go here for a diagram of the S13 SR20DET E5, E6, 62, and 63 ECU pinouts. If you in fact have a Kouki harness, then try to figure out which wires are different. I would imagine its the coilpacks but I havent seen a kouki wiring harness in like 3 years.

yep i believe your right, 3 of the 4 are in different spots, and i think the eccs relay is different too. But why wont my fuel pump turn off after 3 seconds of ignition on and no crank rotation? maybe the fuel pump is wired to a 12v ignition sensor and i have just had them mixed up!

[SpeedRacer1]

Perhaps. Though you may have a bad relay too. Worst case secenerio, I have seen fuel pumps stop priming when the ECU was blown. Happened like 3 times to my friend.

[SpeedRacer1]

Did you still need the pinout for either harness?

[got2b240]

yes please can you give me a pinout for that?I would be soo happy for you to do that for me!

[got2b240]

for the type-x harness please

[SpeedRacer1]

Here is what I figured out. Just looks like the main thing is the 2,3,and coilpacks, and the tachometer wire.

[got2b240]

thank you so verry verry verry much for this information. You have solved my problem with the fuel pump power.

I was tapping off the ecm power for it cause of the mix up of colors !!!!

your the best bro!! THX

damn.. i have searched for over a year for this..luckily all my wiring was fine on my swap, but i had been looking for the differences in pinouts for a long time.

i think i just teared up....lol.. thanks man.

[got2b240]

Tell me about it, Im soo happy i gotten this cause without it my car would be running like ballz

[ibzbro]

you all can thank me, he got all of the wiring from my type x engine .

thank you to LOL
