jeremy_sr510 Posted January 9, 2010 Report Share Posted January 9, 2010 ok how do i wire up the alternator and starter? Quote Link to comment
INDY510 Posted March 18, 2010 Report Share Posted March 18, 2010 I need to know how to properly wire my KA24DE alternator into my 710..... There are two wires off the alt: Wht/red stripe,,,,,,, and a heavy gauge all White wire... I got the wht/red wire wired correctly,,,,,, but the white wire is going directly to the battery with a 80amp alt fuse: Should the white wire go anywhere other than the + side of the battery? It doesn't work like that,,,,,, so it looks like the white wire was supposed to go somewhere else........ :huh: Please help......... thank you Quote Link to comment
JDM510 Posted March 18, 2010 Report Share Posted March 18, 2010 you might have a bad alt..... my alt charges even with none of those 2 wires connected Quote Link to comment
INDY510 Posted March 18, 2010 Report Share Posted March 18, 2010 I had a feeling there were more than two wires........... :unsure: What color, and how many other wires need to be connected?..... Where do they go?.... where do they start??? Quote Link to comment
JDM510 Posted March 18, 2010 Report Share Posted March 18, 2010 on my car their 3 wires 1 fat red and 2 lil white ones like you said one of the whites jumps over to the red and the other goes to my idiot light.... ive heard of people not hooking the idiot light up and having charging issues....

JDM510 Posted March 21, 2010 Report Share Posted March 21, 2010 alt is bad... they do go bad i have 2 on my shelf... and it dont matter if it goes to the starter or the batt it all ends up in the same place just as long as you have the right size wire to go to the starter then from the start to the batt.....

blasta510 Posted April 20, 2010 Report Share Posted April 20, 2010 Does anyone have the original wiring diagram that was posted? It disappeared. Thanks Quote Link to comment
Creepy Cruiser Posted May 1, 2010 Report Share Posted May 1, 2010 I used the diagram in the first post for a KA24DE in my 510, and in 20 minutes the motor started right up and runs great. THANKS!!! My questions is though, I'll be doing a single cam KA soon out of a hardbody, into a buddy of mines trunk, and was wondering if the diagram also crosses to the truck motor wiring? (if not, can somebody point me in the right direction, I did a bunch of searching and kept ending up back here.) Quote Link to comment

I to wondered about the truck single cam wiring. I pulled it back when I did my KA swap in my 620 but it looked like to much of a bitch so I just swapped on the car EFI. To me it looks cleaner and is much more simple. I got all my single cam KA EFI stuff for free, ECU wiring and intake. Most guys don't care for the single cam junk which is good for us datto guys :) Quote Link to comment
Creepy Cruiser Posted May 2, 2010 Report Share Posted May 2, 2010 It went killer. You should have seem me jumping around in the shop, when it fired right up the first time on the first shot. Thank you and everybody else that may have helped out putting that diagram together. I totally agree about swapping the car stuff over, but he has all the stuff on the motor all killer painted, airbrushed, and chromed already, and doesn't want to start all over. Hmmm, I guess I'll start digging into the schematic and see what I can find out. It's got to be somewhat close. Oh, one more thing. Does anyone have an old junk trashed S14 ka harness laying around? I just need the large plug on the distributor. Some whack job that owned the motor before me, cut it off and just shoved the wires in to the distributor and RTV'd them in place. I just need the plug and about 4-5 inches of the wires. Quote Link to comment
sssr20det510 Posted May 11, 2010 Report Share Posted May 11, 2010 ok i thought my ignition switch was bad but i changed it and the same thing, it will start and die unless i power the black with white strip out of the ignition switch. there is 5 wires from the ignition switch and the one i have to power is the one on the end that is by itself if that makes sence ???

inline4 Posted June 2, 2010 Report Share Posted June 2, 2010 should I put the ka wiring on switched power? I have a 75 amp relay sitting here chilling. Quote Link to comment
Creepy Cruiser Posted June 2, 2010 Report Share Posted June 2, 2010 It's interesting that you ask that. I found by looking through the service manual, that it seems to depend on what year it is. Some had a constant and some had key power. So I was wondering the same thing, lol. (If it really mattered or not) Quote Link to comment
inline4 Posted June 17, 2010 Report Share Posted June 17, 2010 is there an easy way to differentiate a 240sx KA24E wiring harness from a 240sx KA24DE harness? Quote Link to comment
2dat0z9 Posted June 17, 2010 Report Share Posted June 17, 2010 on the ka24e intake, do I need the I.A.A. unit, the A.A.C. valve and the Air Regulator?? or can I take them off and plug the wholes on the intake?? Quote Link to comment
johnbureezu Posted September 13, 2010 Report Share Posted September 13, 2010 I was wondering which ECU wire to wire to ground. I didn't see any documentation on it. I am wiring an sr20det into my sand rail and my real problem is somewhere in my relays I think. The black/pink for the fuel pump relay and the red/black for the eccs (ecu) relay are supposed to complete (ground) the circuit, correct? I do not think mine are. Here is the reason: When I take the red/black wire off and ground the relay instead of hooking it up to the red/black, the ECU light turns on. This must mean the computer is not completing the circuit, correct? Also my fuel pump works when connected to direct 12v but not through the relay. My eccs relay is wired: #30 to 12v. #86 to 12v, #87 to blk/wht stripe wire, #85 to blk/red stripe wire I tried to take a pic of my relay but its just too small. Please let me know if you need any pictures of anything or further explination of what I have written. I'm bringing this one back from the dead. I seem to be having a similar problem. I have the relays hooked up using icehouse's diagram. The orange wire from the ecu is hooked up to the black/yellow wire coming from the solenoid. I checked to see if I had an issue with it losing 12v during startup and it seems fine. Now my problem is that I'm not getting signal from the ecu to turn on the fuel pump and ECCS. I have continuity on all wires and the starter cranks. Just no fuel pump or signal from the ecu. What gives? I already replaced the relays and checked all the fuses. When jump a ground to the 85 on the fuel relay it activates, soothe relay is good. Where else can I look? I'm getting close to my wit's end on this one. The grounds on the ecu are fine also. SOS!!!

NCRmtrsprts510 Posted September 14, 2010 Report Share Posted September 14, 2010 Blue/Red wire to IGN relay is used for CA swaps also, not just the SR. FYI for those people doing CA18 swaps. Quote Link to comment
srt4monster Posted October 14, 2010 Report Share Posted October 14, 2010 i cant get my ae86 swapped ca to start. i dont think its getting any spark. i followed the directions step by step. any help would be great. Quote Link to comment
Icehouse Posted January 23, 2011 Author Report Share Posted January 23, 2011 Been updating the thread, more to come. I actually didn't mean to add a reply. Just saying. Quote Link to comment
sanitys Posted January 23, 2011 Report Share Posted January 23, 2011 icehouse, im liking that setup however id like something alittle different (not that you want to do a one off) add 2 relays for headlights, and route all wire outta the bottom with a plug, supply the other side plug with the connectors... edit, oh and have it all enclosed as id like it in the engine bay. would also be nice to have a few extra fuse/relay spots...more of just a food for thought post Quote Link to comment
Laecaon Posted January 23, 2011 Report Share Posted January 23, 2011 Thankyou so much Icehouse! This looks like a much cleaner solution. Glad to see my engine of choice there too (CA18DET) Quote Link to comment

sanitys Posted January 23, 2011 Report Share Posted January 23, 2011 We considered all of these options, later we will most like build other wiring things. good to hear...so what are the advantage of running the PCB over just doing the wiring to the relays? more plug and play, cleaner? Or is this some fail safes put in? are you guys still running power to the cowls all the time like the old diagram? that killed my batt, and my AEM EMS did NOT like it Quote Link to comment
