This a pic of the offending wire plugs. On the left I think we have AT + ABS EFI harness plug E116, on the right I think is MT no ABS engine room harness plug F4. I really have no idea, just kinda wingin' it. Any input is welcome.
I been scratchin my head and I think this harness may have come from an XE? We had one milling around the shop for a few months with a broken heart. IIRC she got her guts yanked, a SOHC oil burner installed, a swat on the a**, and sent down the road.

Hmmm not sure without lookin at one of my cars. I'm out of town at the moment. Have you tried searching through any of the auto to manual how to articles to see if it's mentioned?

I dug thru a few different swap writeups. The one that served best was a 2jz write up, but no relevant info for my needs, other than wire function. I am sure if I knew what input the plug needs I can find it in the harness. I my just be looking at the wrong plug. Also to clarify, this a 1/1990 240 sx MT no abs. I think I said it was an '89 earlier.

Yeah, I see what you're saying (basket case without a basket).
If its all jacked up, and you have harness connections that wont connect, and nothing works, its hard to know where to even start from.
Unfortunately it sounds like you're either going to have to do a ton of research, and re-wire a bunch of the car yourself, or just bite the bullet and buy new harnesses that all fit together.

The sucky part is the harness is pristine. I can't believe the FSM wiring schematic does not cover the inputs of that MT plug. I will give a call to the wiring harness guys.

I just got off the phone with them and they do not make the harness for a stock KA24e. So no luck there. I asked if he could tell me the function of the F4/E115 plug, but no dice. So I will just have to try a few other things and see what happens. Time to bust out the ol' volt meter and soldering iron.

I could have sworn that was something that plugged directly into the ECU, but I could be wrong.

You could try making your own dedicated thread for this in the 240 section. You'll get a lot more people looking at it that way.

Thanks Papa. I'll give it a shot. If anyone else does happen across this thread, I would like to know the function of the plug pictured above, possibly engine room harness connector E115. It comes through the firewall from the fender.
The FSM gives nothing that I can find about this connector. Only the AT versions are shown on the schematic.

You'd probably want a little less offset than that with an 8.5, but they shouuuuld fit, provided the bolt pattern is correct.

Found plug! FSM pg 896. "Ya gotta get in there and dig, son!"
The plug pictured is the cruise ctrl plug. Or ASCD for the fancy folk. So the plug I'm looking for must be stuffed up in the firewall still.

I'm a little strapped for cash at the moment, I'm expecting a baby by May and I'm trying to get my car a little further along before the due date. My question is should I chance buying a set of used JIC Coilovers off eBay for 650 or just buy a brand new set of Megan EZ streets for 50 more? I wanted a better set but I cannot afford the extra money now to buy them. I've read some good reviews on the ez streets but I don't like the fact there's no camber plates. I'm concerned on taking a chance on the used coils not knowing the condition an abuse they have taken.

If you can't swing an extra 50 bucks, you probably shouldn't buy any at all, considering you have a baby on the way.

I wouldn't want a set of coilovers that didn't come with camber plates though. Is this your main transportation, or is it a project car?

Project at the moment but has been a daily for 7 years and will go back to it when I finish a few small things. I put bedliner in the interior, swapped to non hicas subframe, bushings, etc. The 50 isn't the problem. An extra 300+ for some good coilovers is the problem. I wanted to get some quality coils, that's why I thought about used ones but then i thought about what kind of damage they may have recieved during their use. I've read before about guys buying used coils but you never really know what your getting on eBay. I know some can be rebuilt, but if it's a few hundred alone I guess I'd be better off getting a 900-1000 set. And We are definitely on the same page about the camber plates but unfortunately they do not offer them on that particular set. I actually purchased the isis basic coils last November twice only to find out after the fact they were out of stock at both companies and then told me they (isis) supposedly quit making them. about a month ago I saw a thread where a guy had a set and one broke. Idk if it was a fluke or what.

Yeah who knows... guess you'll have to trust the seller and what he says the history of the parts are.

would bad (2 year old) gas cause these symptoms on a s13 kade?
rough and fluctuating idle
bogs when i give it throttle
seem to be running lean. exhaust mani gets super hot way too quick
ive check the codes a bunch and every time i dont get any. ive swapped mafs and there was no change and the knock sensor is new and ive reset the timing. other than the gas, i can only think its a vac leak somewhere

If you don't need the coils right away save up another couple hundred and snag a set of BCs. 240sxmotoring is running a deal right now on s13 stance coils for $980, though.

Some of the fitment guys like the megans because they can fit a 10 upfront without a crazy low offset to clear the coil.

my question is, on the s13 trans harness, there are two connectors attached to the positive battery terminal that connect to the chassis harness. Do I need these? I intend to put the battery in the trunk of the car, and would like to remove the terminal completel to extend the power wire to the battery.

It could, and should be eliminated as a variable before really spending money on other things, but most likely there is something else going on.
You could always try to find someone around with a wideband O2 sensor too that could tell you if you're truly lean.

Car: S13 rb20det swap

Post

Okay i have a 90 s13, rb20det swap just bought the car. Ran the other day then when i parked it i stalled it. Went back to start it up to drive and it fired then shut off like it ran out of gas. Tried priming the fuel pump, nothing. So i hardwired my fuel pump to a 15amp toggle, pump works perfect. Go to start the car, still no start, getting fuel and spark. I checked the ecu and it was throwing code 55, someone please help im new to these 240s, still love it tho..update on the car...my cas works i turned it by hand and my coils fired, just still no injector pluse but 12v to the harness. Raining today but im leaning towards a rigged up wire coming loose under my fuse box from previous owner. The better question is.. does my fuel pump relay control my injector pluse as well as the fuel pump??? Any help is highly appreciated

Hey everyone! (this is my first post so go easy on me :crazy: )

Tomorrow I am going to go look at this 240: http://orlando.craigslist.org/cto/4722438712.html

What are the main things I should look out for? How can I talk the price down? And do you think she would make a reliable daily with all those miles? Thanks everyone! :bowrofl:


Also when the ad says the engine was "refreshed" (according to him) the last owner replaced the o-rings, head gasket, rod bearings, and he thinks the timing chain

Its not an automatic, and these plugs connect to the chassis harness by the fusebox.
Just curious as to what they do.

Seems like a good deal, runs good with cold a/c? Reminds me of my white s13 when I got it, paid 1K but that was 9 years ago and no a/c or coilovers.

Check these things:
-Starts up within a few turns
-Idles strong and comes to a stop without dying
-Gauges work / speedo works
-Smoking out of the tail pipe
-Gear grinding when cold
-Shaky shifter while taking off in first
-Thumps or thuds while driving

Any of these things can be used to talk down the price, just factor in what it costs to fix it and try and get him to come down that much on the price. Overall, these days, seems like a good deal even with some of the issues noted above. Good luck

Thank you GTR PrYdE for the reply. Unfortunately I woke up to a text from the guy saying he sold it... Oh well, I found an even better car in better condition: http://tampa.craigslist.org/psc/cto/4707013928.html

There seems to be only one problem with it, the guy is asking 4200 DOLLARS :wtf2:
It did say or best offer so what do you guys think I should start off with as the offer? I'm afraid if I lowball too low hes gonna just shut me down and feel insulted (thus no car).
Any ideas? Thanks!
