In Topic: How to wire a KA, CA, SR, and VG into anything

12 November 2017 - 06:59 PM

Hello Everyone!


Ive been gone for a bit, but working hard. I'm trying to get the 521 running and having some problems getting the motor running.


S13 KA24DE with manual ecu ::::::::::::: msd 2225 fuel pump 


I started following an old diagram that didn't work. After reading everything I could find online I'm more confused now then when I started.




So far I have tested the following:


Dizzy has spark

Injectors have power confirmed with NOID

TPS has normal functions based on testing I found online

MaFF has power to it

Fuel rail is getting gas


I have just found the updated diagram on this forum and wired canam box accordingly, but fuel pump relay not working properly. I have a few questions about this new diagram.




1. What is going on int the areas I circled in red? It looks like a wire going from 86 to 30 to me, but not sure how to hook that up.

2. 46 & 109 look like they go directly to 30 but is also listed as going to ecu bup (currently I have these 2 only going to ecu bup).

3. What is the ground at the bottom of the diagram? 

4. What happened to the O2 sensor wire that was originally in the first diagram?


Here is how my canam box is wired. Don't look at all my red wires!!! They are labeled!




Anyone see anything wrong with my wiring?


Also is a fuel pressure regulator required?
