So I followed the wiring diagram that Floyd posted and my SAFC-II( Apexi AFCNeo) wont turn on or anything. Honestly I want this in to help tune my car better. I NEED HELP BAD!!!! Also I hook it up to a 12 Volt Power supply and it works fine sooooo, if anything i could not be getting power to the unit.

 

We can't give you help unless you give us some information to work with. All we know now is that you hooked it up and you're not getting power. Did you check the wires with a multimeter to see if they are getting power?

 

My wiring diagram was for a 2003. I am not sure if a 2004 is different. If I have some time I will take a look and see on webtech.

 

Ok, sweet thanks for the help!

Yeah totally forgot about that its an 04 Accent 1.6l Alpha. Hope thats enough, also I tried wiring it to a positive and ground wire that goes to the ECU and still didnt even turn on. I connect the SAFC-II to a power supply, and it turns on and works fine.

 

I♦t sounds like you may be using the wrong power, ground, and remote wires

 

So I followed the MAP sensor wire and its pick for 04, but were is the throttle postion sensor located, and RPM sensor wire located?

 

It should be the same wire diagram FLoyd...I used the wire diagram from an 02 and mine worked just fine.

 

Hmm...the wiring diagram from the 02 doesn't match my 03 at all. I wonder if 03 is an odd year where they changed it for some reason and then switched back?

There are major differences between my wiring (from my factory ETM and actually on the car) and DREROB's ECU pinout chart. they're about 90% the same but that's still 10% different.

 

I tried Floyd's diagram and it didn't work for me. I managed to find the wires I needed. I just need to find the RPM sensor wire though. But I do not think the 04s are the same as the 03s
