hey guys, im a newb here, this is my first post, yay for me! Anyway, im not new to engines, ive been building honda's my whole life (dont hold it against me), but i recked my beloved hatch a while back and decided to get a 240, so i bought a 1989 240 sx with a da24de dual cam engine in it, problem is that it doesnt have a harness on it, the ecu i have is from a 1991 ka24de. I have access to a 1995 240 sx and i was wondering if i could use the engine harness and ecu from that car? And if so what kind of modifications would i have to make? what parts can i use off the 1995 car that would make the 1989 better? Just so you guys know im planning on going ka-t since im new, i figured ka's are cheap to find around here, so it would be the best route, plus it looks fun and i can afford to make mistakes (since i know i will since im kind of new to nissan). Thanks for the help guys, ive done a little searching and couldnt find too mcuh on this.

I really just need to know if a 1995 harness and ecu will work on a dual cam ka in a 1989 car...(the ka is from a 1992 240)

dunno

Need a little more information. Find out if your ECU is an earlier 95 (OBD-I) or later 95 (OBD-II). If it's OBD-I, you should be fine. If not, you need to cut the wipers out of it and rewire F3 to work with the S13 dash connector.

ok how can i tell the obd1 from the obd2? and if it is obd1 will everything just plug right in with no issues? i cant seem to find a real full writeup on the swap and the wiring involved, it seems some have to rewire the dash connector and some dont, thats what im mostly worried about, is how to rewire the dash connector. If the harness and ecu are obd2 can i still use them on my obd1 engine? Its the only local dual cam 240 i could find so im hoping i can use it...

you know going from honda to nissan its like Gay to straight. OBD1 comes on 95 240sxs abd OBD2 comes on 96,97,98 240sxs. i`m not too sureif you can use S14 wires harnesses , on an s13 . Try http://www.courtesyparts.com/secondtier_s13.html i know they have brand new OE items that arent at the dealer price

iono about the gay to strait thing, i enjoyed honda's but its time to move on, and something about the rear wheel drive is awesome, anyway, i have an s14 harness and i jsut want to know if its possible to use it, and if i need to modify it someone tell me how!!! lol, unless someone has a s13 harness they want to sell me?


and any links to good ka24e to ka24de writeup's would be AWESOME...

Funny you mention that, as it seems that you have failed to search adequately... There has been a couple of threads about it within the last week, and all of which led to my own posting of this link:

http://www.zilvia.net/f/showthread.php?t=33502

... found in the Frequently Asked Questions area down there, a place where every new member seems to not know how to fucking use... Failure to search moving forward will cause us to set the entire state of Kentucky on fire

Get a 91-94 harness and ECU, direct plug in outside and a few cuts inside. The 95-98 harness will require significantly more work and lengthening for the entire underhood portion.

hey, dont be a jerk, i searched, came up with mostly useless stuff, i happened to find the faq last night and read it, but my main question was what would be involved in getting a 1995 harness to work, which i actually still HAVENT found in my searchs, i KNOW how to use a search, but after a few hours of reading useless threads i figured id ask, so keep your pissed offness to yourself in my thread...

Phlip

Hey, Russ posted an answer to your question just before you responded to me, 7 hours and 10 minutes before you responded to me, and yes I will continue to be a jerk, because I enjoy it... No one said I was pissed off, I am just a sociopath. I don't hate you, I hate your parents for having you

well tell them about it, not me, i jsut asked a question, no need to flame, but i understand, flaming can be very enjoyable. I would LOVE it if someone would post me a link to a s14 into a 89, that would make me shut up

Phlip

Hey, jackass, I will tell you that I have an S14 engine in an 89... The engine is out of a 95, I have a harness out of a DOHC S13, the ECU is from a 91. Use the harness corresponding to the ECU you use, but keep in mind that this will be less of a pain in the ass if you use them from a 91-94, as R240NA said... There is no link because I did all the necessary searching befor sourcing parts.

ok well, i have a ka out of a 1992, but i have the harness and ecu from a 1995, HOW DO I WIRE THE DASH HARNESS INTO IT...

projectRDM

How you read a fucking word in this thread? At all? Apparently not.

First off, buy or download an FSM. Lazy ass people who cry for help and wish to be spoonfed like you make us all sick, and no one is going to give you the time of day if you don't at least try.

Secondly, to use an S14 harness in an S13 you'll need to do what I listed above, Cut off F3, extend and wire in the dash plug, then extend all the ECCS wires several feet, run them outside, and tie into to the underhood plugs. If you haven't researched the swap at all then you'll have no idea what I just said, which further proves you haven't done a damn thing to prepare for what you're attempting.
An S14 motor is no different other than a few small changes than an S13 motor and using an S13 harness/ECU is a DIRECT PLUG IN with everything already the right length.
But if you're insistent upon using the S14 parts at least look at a fucking diagram of both plugs, it's simple to figure out if you put forth a little effort.

And I will tell you, that Russ knows the wiring to EVERY S-Chassis car by color without having a FSM in hand by heart. The question has been answered repeatedly, yet you continue to re-present the same damn questions, someone please lock this thread, I have thrown enough temper tantrums since this weekend.

I think jarvis's questions have been answered a couple time's. This is a comon swap so there are many write-ups that have been showen to you.

Search!!! and yee shall receive.
