qwik510 Posted November 27, 2008 Report Share Posted November 27, 2008 Just be like me, I call it the 3 year plan, I get parts and don't do anything with them for around 3 years, sometimes even longer. I had my KA before I even had the 620. The trick is to be on the look out for one know, if a good deal comes up grab it, if not keep waiting :D I am on the 3 year plan too. maybe a bit more. I bought my 2 door stocker 3+ years ago with plans for the VG swap. Collected parts since then and finally started last month. Better to be prepared. 1 Quote Link to comment
boltupright Posted November 27, 2008 Report Share Posted November 27, 2008 That diagram is very nice. Great job on it. Now if only someone did one like that for the VG30 swap. Does anyone know of one for the VG30 engine?? http://vondrachek.org/automotive/datsuns/vg30_project/ This site has a lot of good VG info 1 Quote Link to comment
wheruat Posted December 11, 2008 Report Share Posted December 11, 2008 hello everyone new to this site. well im doing the wiring right now for the sr20 was wondering. Im using the Power FC D-Jetro model and was wondering if its ok to remove the other wires and plugs that are not being used out of the big blue clip or will it mess up the system. thx 1 Quote Link to comment
fiveNdime Posted December 13, 2008 Report Share Posted December 13, 2008 Does anyone know if the "SR20det wiring to 510" works for the FJ20det? I am going to be tackling this in the future and was just wondering. Thanks 1 Quote Link to comment
nismopu Posted December 15, 2008 Report Share Posted December 15, 2008 dont you have an stand alone that needs a car to be used in? IMO it would be far superior to that old analog style ecu. 1 Quote Link to comment
dimeofftheline Posted December 16, 2008 Report Share Posted December 16, 2008 Does anyone know the function of the resistor/condenser on the S13 KA24DE wiring. I am seeing power at B/R on the F30 plug, but no power from the LG/B wire. Should that light green wire have power (when the key is ON)? Maybe someone can probe theirs with a test light for me:D. I have the harness wired up just as y'all do and I am not getting spark. Any insight is appreciated. 1 Quote Link to comment
slodat Posted December 16, 2008 Report Share Posted December 16, 2008 Any photos of the car Alex?? 1 Quote Link to comment
dimeofftheline Posted December 16, 2008 Report Share Posted December 16, 2008 Yeah, though it doesn't look a whole lot different than the last time you would've seen it. More here: http://tinyurl.com/6p5tuw 1 Quote Link to comment
Icehouse Posted December 16, 2008 Author Report Share Posted December 16, 2008 What makes you think thats why it won't get spark? Do you have power at the black/red? Do you have a good ground from the engine to the chassis? 1 Quote Link to comment
dimeofftheline Posted December 16, 2008 Report Share Posted December 16, 2008 I was just pondering about the light green wire... I do have power at the black/red wire. I don't have a very big wire to ground the engine to the body. I suppose that would be a good thing to add. 1 Quote Link to comment
Icehouse Posted December 16, 2008 Author Report Share Posted December 16, 2008 Well as long as you have one it should work, but it's good to have a nice size ground, remember that there is a huge gauge wire running to the starter, just as much power needs to return to the battery to complete the circuit. If your ground is to small it could melt if the engine cranks a lot, like in your case since you have no spark. I would just make sure the wire goes to the points shown in the diagram, if it does it should work fine. Testing for power can damage signal circuits if they aren't designed for the load of a test light. Did you personally see the engine run before you bought it? Where you testing for spark from the coil or through the cap and plug wires? 2 Quote Link to comment
dimeofftheline Posted December 16, 2008 Report Share Posted December 16, 2008 I didn't personally see the engine run, so I can only take the dude's word for it. The coil is out of a friend's car that runs so I know its good. I've been checking spark both from the main coil lead and from cap/plug wire, holding 1/16" or so from a ground. Everything seems to be hooked up right so it's probably a matter of double checking things. My ECCS relay comes on with switched power and the fuel pump relay does it's timer thing so I guess that's a step in the right direction. 1 Quote Link to comment
Icehouse Posted December 16, 2008 Author Report Share Posted December 16, 2008 I think that little chip has to be grounded... maybe... I forget but I think in the factory location it is. Try that. 1 Quote Link to comment
nismopu Posted December 16, 2008 Report Share Posted December 16, 2008 Ice you talking about that little black ground that goes on the ignitor? If so yes that needs to be hooked up or else what your descrbing will inhibit spark. peace. 1 Quote Link to comment

Its been a while since I dealt with that chip but I remember THINK I remember the whole housing on KA's being grounded to the chassis.. 1 Quote Link to comment
nismopu Posted December 17, 2008 Report Share Posted December 17, 2008 yeah the little ignitor/coil housing grounds to the chassis but has a small tab on it that the black connector from the harness attaches too. 1 Quote Link to comment
inline4 Posted January 23, 2009 Report Share Posted January 23, 2009 what is the minimum amp rating one can use relay wise to wire up the harness? also why would some relays be less optimal for usage as opposed to the bosch style 30/40 that you guys are using? 1 Quote Link to comment
spoolinitup33 Posted February 4, 2009 Report Share Posted February 4, 2009 Just a little FYI, if you have a new wiring harness, the fuel pump relay wire is black & purple, not black & pink. I guess it fades after a while and looks pink! 1 Quote Link to comment
DatsunDimer Posted February 22, 2009 Report Share Posted February 22, 2009 Silly question probably. I have an aftermarket wiring harness and I am trying to identify specifically the "fuse block" black/white wire in the wiring diagram in relation to what I need to look for in my harness. Any help? Thanks 1 Quote Link to comment
Icehouse Posted February 22, 2009 Author Report Share Posted February 22, 2009 The black with white stripe is basically a wire that is powered up with key on and key in cranking position. Basically it just turns on the EFI, you could hook it to a toggle switch if you wanted :D 1 Quote Link to comment
datzenmike Posted February 22, 2009 Report Share Posted February 22, 2009 Jeff, I have a harness and ecu from an '85 CA18ET. Is it like the newer KA EFI or is it still the older Jet-tronic /batch fire of the 280zx and early 200sx? 1 Quote Link to comment
Icehouse Posted February 22, 2009 Author Report Share Posted February 22, 2009 Mike that was the first engine I ever wired into a dime :D I actually can't really remember how it goes... haha Do you have the wiring diagram? If you want to send it to me I could figure it out for you :D 1 Quote Link to comment
datzenmike Posted February 23, 2009 Report Share Posted February 23, 2009 No good diagram, I just wondered if it was more advanced than the early '80s 200sx system. 1 Quote Link to comment
Icehouse Posted February 23, 2009 Author Report Share Posted February 23, 2009 I'm sure it is, since is has a MAF instead of the flapper. 1 Quote Link to comment
lownslow Posted March 27, 2009 Report Share Posted March 27, 2009 I'm new here. I was wondering if any one had a wiring diagram for the s14 engine harness to a 620. I have a ka24de going into a 78' 620. 1 Quote Link to comment
