freekwonder Posted April 2, 2012 Report Share Posted April 2, 2012 Alright I'm being an idiot looking for a wiring diagram for a S14 KA24DE. I've tried the FSM manuals, but I'm just not seeing it. Where is it at? And yes I know I'm an idiot. Quote Link to comment

Where is it at? And yes I know I'm an idiot. Try this, http://www.nicoclub.com/FSM/240sx/1995/EC.pdf page 7 btw of the pdf. Quote Link to comment
freekwonder Posted April 3, 2012 Report Share Posted April 3, 2012 Yeah I've seen that, but I was hoping to find something like the foldouts in the 91-94 FMS. Quote Link to comment
MYTE_510 Posted April 5, 2012 Report Share Posted April 5, 2012 i like pictures! anyone have one of there box wired into a KA24E? i am looking over these diagrams and they are not computing... i need visual aids!!! 1 Quote Link to comment
Icoblue Posted April 6, 2012 Report Share Posted April 6, 2012 Jeff, I'd like to order one of these for my KA swap. I'm using the KA twin cam out of a 2000 Frontier. This shouldn't matter at all, right? The engine control wiring should be exactly the same as the 240SX wiring, right? I'm in the process of separating the engine control wiring from the body harness. Big pain in the ass, unfortunately no wrecker or speed shop in my area has a 240SX harness available. You've wired lots of engines; any idea what's different about the truck KA? If you PM me paypal info I'll get a payment out to right now. Quote Link to comment
Hardwyre Posted April 6, 2012 Report Share Posted April 6, 2012 If I can do it, you can do it. The hardest part of it is getting used to how the ECU grounds everything instead of using power through the relays. That really threw me off! My Megasquirt does the same thing. It threw me off for a long minute. Then I realized that it was because it puts less load on the ECU. Quote Link to comment
Laecaon Posted April 7, 2012 Report Share Posted April 7, 2012 Yeah I've seen that, but I was hoping to find something like the foldouts in the 91-94 FMS. I found you a pinout for a 95 ecu... http://www.240sx.org/faq/articles/95_ecu_pinout.htm Quote Link to comment
freekwonder Posted April 7, 2012 Report Share Posted April 7, 2012 That helps, thanks. Quote Link to comment
Adam134 Posted April 8, 2012 Report Share Posted April 8, 2012 Now this is going to sound absolutely ridiculous but I'm confused being that this is my first attempt at wiring. Fabrication, bodywork, paint no problem but wiring is a handicap of mine.. I just picked up my S13 redtop SR20 and I have my can am box.. Where are the majority of these wires being found? The way I understand it is.. The wires from the ECU to sensors etc stay untouched, and then the wires for this box come off of seperate plugs on the harness? I know the answer is probably so simple I'll look like a tool afterwards but as I said I just can't seem to figure it out and where I'm doing the swap this week I'll be without internet for the most part so research time will be over. 1 Quote Link to comment

The wires are coming directly from the ECU. That is why the pin numbers are given. Most of the wires will still go to the factory sensors and stuff. But a few have to be adapted. Since largely Datsun wiring is old and not up to snuff for the demands of the ECU (mainly due to the way it is wired), we relay things. This box simply turns things on when they are supposed to. Like part of the ECU and the FP. So simply find the wire color coming from the ecu, you may need to look at the pin on the ecu to figure out which wire? And then simply attach it to the box. The Black/White wire from the 510 harness is simply ignition power from the ignition. 1 Quote Link to comment

Guess wiring is the least of my worries this week during my swap. Quote Link to comment
ratsunissan Posted April 22, 2012 Report Share Posted April 22, 2012 where can i buy one of these? im swaping a ka24de-t into a 720 and have no clue what to do to wire this shit.. Quote Link to comment
Laecaon Posted April 23, 2012 Report Share Posted April 23, 2012 where can i buy one of these? im swaping a ka24de-t into a 720 and have no clue what to do to wire this shit.. Well, look at the for sale section! Its a pinned topic. Also, I know these look easy, but its still a good idea to raise your knowledge of wiring from "no clue" Quote Link to comment
frisco510 Posted April 23, 2012 Report Share Posted April 23, 2012 Hay need some help it won't start have a 72 wagon ka24de 5speed stock rebuild I hooked up the can/am box my ecu red light turns on but when I crank it turns off? Is that how it is Quote Link to comment
ratsunissan Posted April 24, 2012 Report Share Posted April 24, 2012 alright thanks..i mean i have a good idea but i never re-wired a hole car before Quote Link to comment
Michael.flee92 Posted May 7, 2012 Report Share Posted May 7, 2012 So on the part where it says relay on the diagram, do i need to get the relay connector with the actual relays? Stupid question lol i know. It would seem that way right? Thanks. Quote Link to comment
Michael.flee92 Posted May 7, 2012 Report Share Posted May 7, 2012 Oh and another question... I have the upper ka24e engine harness... is that the only one i need? Quote Link to comment
MYTE_510 Posted May 7, 2012 Report Share Posted May 7, 2012 you dont need any extra relays at all and all the wires minus 3 come from the small connector right next to the ECU connection. The TOP(black) is my ground The 4th Down is my Black/white from the Fues block The BOTTOM (green) is to my Fuel pump all the other wires were nicely found in that smaller connector(there are some that arent used just match your colors and you will be fine). i placed my box close to my ECU and i didnt even have to extend any wires. 2 Quote Link to comment

Okay so are the wires coming out of the canam connect to the ecu/eccs part or are they going out to the actual part that it powers? Quote Link to comment
Laecaon Posted May 10, 2012 Report Share Posted May 10, 2012 Okay so are the wires coming out of the canam connect to the ecu/eccs part or are they going out to the actual part that it powers? They go exactly where the Can/Am is labled for them to go. Basically all go to the ECU, minus the one that feeds the FP, the wire that is for keyed power (from the cars ignition switch) All the Can/Am box does is turn on the ECU at appropriate timing, either by providing power or providing a ground.

Thank you! I have a few questions more questions if no one minds lol... Okay so the power transistor and ignition coil wires... Keep them right? I will be using the msd blaster set up. So from reading write up on wiring those i will need to keep them? Just double checking and triple checking. Second question... Thermal transmitter... It came off the white connector next to the ecu that i cut. Do i need this? and if i do where does this thing wire up to/ does it wire back into the ecu? Quote Link to comment
MYTE_510 Posted May 11, 2012 Report Share Posted May 11, 2012 i didnt actually get rid of any wires i didnt use in that connector just in case. i wasnt sure so i left them alone just didnt hook mine up to anything. assuming you match your colors and use the wires your suppose to it should fire up. i have a SOHC KA and mine worked first time i tried.

montanosvg30 Posted May 12, 2012 Report Share Posted May 12, 2012 I need some help..... I just finished conecting the ECU to the CAN/AM. The problem I have is that I dont know how to connect the wires from the ignition coil. I have th FSM, but I'm not too good at figuring out wiring. Quote Link to comment

Well i cut it like that pic above... and the thermal transmitter was in that connector and not connected anywhere else from what i can see... So does anyone know if i need that? I'm thinking I might lol But Lets hope i dont :P Quote Link to comment
