in need of some help

[bladestonez]

i just bought my 89 240.

it has a de swap done by someone who didnt know what they were doing and idk what kind of wiring mess i have and would like some insight.

car came with 3 ecus an s13 sohc manual (stock) s13 de auto (connected) and an s14 de. idk what engine harness they used but i can only find one unconnected plug on the motor and there are a ton of unused harness plugs. im also concerned about the auto ecu will that work with a manual? if anyone has some insight on what i can do or sell me an s13 de engine harness and manual ecu if i actually need one that would be great.

the auto ecu will work fine, you will just get a check engine light for the neutral safety switch, any pictures of where the harness is not connected?

Auto ecu is fine for manual. Pics would definitely help. One thing you could check are a couple of plugs behind the head near the firewall. S13 ka's had a couple solenoids for scv's and other emissions. If it has an s13 ecu, it's most likely an s13 de with an s13 harness

auto ecu works fine on manual, don't worry about it. the auto ecu is actually "better" than manual ecu, since the auto ecu doesn't have the speed cut that the manual ecu does.

i will get some pics a little later but several of the plugs are up front between the injectors and the coil plugs and i cant find anything except a plug on the left fron corner of the head but theres no mating connector for it.

ok got a few pictures not great quality but all i have is my phone hopefully they will help someone help me.

Somebody correct me if I'm wrong but
top is TPS
second picture is Knock Sensor and ?
third are for MAF and a sensor that goes into the air box
fourth the bottom plug hooks up to a vacuum pump used for emissions.. the rest kinda looks like a mess..
How is it running?
Is it running at all?

my advise is, go out to a wrecking yard and get another harness, Do you have any pictures of the entire engine bay? The car will not run if most of these items aren't hooked up. Do you have the MAF? BTW get a new hose that connects from intake to the manifold, Oh and no problem mang!

yeah i have the maf i completly forgot to put it on though lol. ive been trying to find another not as fucked up harness but no one has s13 de harnesses everyone and there dog has s14 ones but from what ive been told and can see from the s14 harness i have is they are entirly different and my s13 engine is missing tons of sensors for the obd2... and none of the scrap yards or junkyards have any 240s around here.... up here in the midwest these things are pretty few and far between.

Looks like you have an aftermarket intake pipe, might need a coupler and adapter S13's are OBD1 try and find a harness on here on the FS thread or post a thread on the WTB thread

[Eramo323]

might just want to pick up a fan shroud too

yeah its an aftermarket intake and ignition coil, i have the couplers and everything just need a filter lol... and i cant post in the marketplace stupid 30 day rule, like how is a newbie supposed to get started when they cant get parts, kinda bs if you ask me.

It works out tho.. there's a lot of scammers and i kinda get why they do it,
Try searching Craigslist for the meantime or Ebay

ebay has none and like i said the cars are hard to come by around here parts are almost harder to find. since i know what all the plugs are for now it should be somewhat easy to fix the harness ( odd connector on the head is coolant temp i found out btw looking into electric fans). so its just a matter of plugging everything in hooking up an air filter and hopefully she starts and the battery will hold a charge. i must thank you again for your help you have definitly given me a good welcome into a new nissan world and i appriciate not being treated as a complete idiot
