Hello All,

 

A few questions;

 

KA24DE swap into a 510; Reading thru this post; it looks like its only 8 -10 wires to get the engine running.  These wires are mated to the existing 510's electrical system.

I was thinking of using a Racing style switch panel.   (Push Start) (Fans) (ignition) (Fuel Pump) (Power) (?) using relays.  Using this method, is it save to assume; I not need to use the wires from the KA harness?  

 

Also,  Does the ECU need to be re-flashed to eliminate sensors and plugs not in use any more?

 

Thank you 

BUMP  Anyone?

No re-flash required.  Just follow the drawing at the beginning of the thread.  CAN/AM box not required just makes things clean and easier to install.

Thank you for the reply ICEHouse. What about hooking up the Fans, Fuel Pump and push start to switch panel?   Do I just leave them off the harness? 

one last question;  Do you know what wires can be removed to clean up the harness?

need help with wiring a s13 ka24de into a 521.  figured all the wires out off the diagram from page one except the brown wire going to the iacv to the run on the can am box.  I actually think i do have it right but wanna confirm.  i dont have a brown wire coming out of the plug going in the iacv.  i have a blue with green strip coming off that plug that goes under the intake to the iacv and air regulator and the other end goes into the grey plug that has my ecu bup ecss 1 and run 2 and is the only un accounted for wire so i think its it.  can anyone confirm this?  im sure if i had some pictures that would help also but atm i dont.  thank you any that can help!

I think the 3 plugs on the back of the intake all go to a big grey plug ... you need the other side of that big plug to see which wire is brown

Bro just look for exit pin out of your engine and ecu
Tap In to the wire there for your iacv
It should be brown there number 113 on a 1991/94
Ka24de

Hope this helps

thank you for the reply guys, but...

yes the other end of that big grey plug has all the wires i need... but there isnt a brown.. there is only a blue with green stripe.  ive used the diagram from page one of this thread, which says its a brown wire, and the diagram below shows its a brown wire, but i dont have said brown wire??

the wire from pin 113 is light blue and goes from the ecu to the grey plug going into the intake which is where from the diagram below and page 1 and everthing else ive read and found there should be a brown wire coming out of that same plug that connects to the grey plug ess and ecc bup and such.  everything else im confident is wired correctly. 

 

This is designed for my project.  Yours may not look exactly like this.

 

This will be a stripped down efi harness with only whats needed

 

This is for a Datsun 620

 

Am I missing anything?

I think Josh is running that same thing on his 510 with the turbo KA 510, he's changed the title a few times so at the moment I can't think of it.

Hey all,

I wanted to sanity check my plan with you guys to make sure I'm not going to fry anything.

 

I've got two fuel pumps in my fuel system - a low pressure pump before the surge tank and a high pressure pump for after the surge tank.  I also have separate relays for these pumps.  My plan was to use FP 1 from the CAN AM to trigger the other relays instead of a single pump like most folks do.  Does this seem sane?

 

 

Icehouse,

I've got an S12 VG30E ECU, so if you're still wanting to help somebody wire up one of these I'm all game :)

Yeah I need to figure out if the wiring for the fuel pump.  I had a fix written down.  Now just to remember where it was written down.....

S13 KA24DE wiring

These are the connectors that you need.

I have more diagrams for S14 KA24DE, S13 SR20DET, S14 SR20DET kouki and zenki, LS1, VK56DE. I'll post them eventually.

 

On the S13 KA - does the orange wire off the ECU for "starter signal" have to route back to the fuse box/ignition or to the Can/Am box?

Also, does the wiring box need power directly from the battery with that 70amp fuse?

 

edit: figured it out - still wondering about the starter signal.
