Difference between ka24de auto and manual engine harness?

[s3teen]

So please read before cluttering this thread!

MY cousin has a 90 s13 with a Ka24e (single cam) automatic... He want's to swap in a ka24de (Dual cam) and stay autotragic. (He can't drive a stick). So the Dual Cam he is buying is a 5spd.

My question is, So would he need to buy a whole new engine harness/auto dohc ecu? Anyone ever ran into this problem?

Dude he's like 15 just got his liscense and My uncle doesn't want him to be racing around losing his liscense doing stupid s***. I understand where your coming from but if he want's to learn in the future it wouldn't be that hard. And like I said, please don't clutter this thread with useless info. I need HELP as to whether I can use the main engine harness with an auto ecu? AnY help????????

[locoluna825]

why does he need a dual cam? your making it harder on your selves ill buy that dual cam and 5spd form him.. and ill give you a auto sohc problem solved.

why are you buying a dohc get a sohc this is a** backwards shiit. ppl dont buy a dual overhead cam and manual trans to go and put it in a sohc and change it too a auto. your gonna need the entire engine harness and dash harness and ecu just to do the dohc right, then you want to convert it to a auto ? get a sohc i got one right here. to much trouble unles syou keep the manual.

and just because if it were to have a manual doesn't mean its gonna be a race car. teach the boy drive a manual and to drive like a normal person i don't get your uncles logic. hes worried about something he hasn't even taught his kid not to do? hes not gonna be racing while learning to drive a stick trust me on this. IF he does he'll blow the damn thing up. just swap the whole damn thing in and see what happens tell us then.

Jesus....please f*cking help me! lolOnce again off topic! DOES ANYONE KNOW IF THE ENGINE HARNESS OUT OF A KA24DE ARE THE SAME FROM AUTO OR MANUAL. So basically the wiring harness that goes to the ecu! Is that the same in an auto and manual or are some of the wires different????

[locoluna825]

there different there f***ing different the auto were equipped with a different lower engine harness than the manuals. go get another sohc damn it

[s3teen]

Ok now we are getting somewhere! So just the lower harness is different right? So you basically are off topic on both of your post in this thread. I just want to know if I can use a 5spd engine harness(upper) to go with an autotragic transmission????That's all sorry if it bugs you.

[locoluna825]

it doesn't bug me im just so sad to see that setup murdered, you gonna have problems..... why did that kid buy a dohc and manual anyhow? hes got different plans then you guys lol

[s3teen]

For sure So anyone no if an automatic engine harness (upper that goes to ecu) is same as a manual engine harness (UPPER)?????????

[the converted]

No it is different. There are wires to go the the TCU that aren't there on the manual harness.

[s3teen]

No it is different. There are wires to go the the TCU that aren't there on the manual harness.

ZOMG!!!! THANK YOU FOR A LEGIT REPLY!!! ^thanks mods can close/delete thread if needed be

Nothing ever goes away so other people can search for things. That's also why it would be helpful to title the thread something like "Difference between auto and manual ka24de engine harness"

[s3teen]

fixed

does anyone know what it takes to make a dohc engine harness that came off an automatic 240 work on a 5 speed 240? i got my harness routed and everything and my fuel pump isnt priming and im pretty sure its because the harness i put in came out of an automatic 240 and my 240 is an origional 5 speed car. theres a extra plug under the dash. id like to not have to take the harness out and replace it with another because im sure its just some wires that need to be jumped and that seems easier than ripping out the harness and doin it all over again

[the converted]

Wouldn't make any difference at all. You might have missed a connection, or possibly a bad relay, but there are no differences in the harness that would lead to the fuel pump not working. Also, are you sure that the ECU is working properly?

[jeff420]

ill have to check grounds. put in 2 good workin ecu's so i know its not the ecu. fuel pump may have taken a s*** i dunno. ive read in other threads that the auto engine harness can work but you have to do somethin, just cant find the info on what has to be done. i just assumed the plug under the dash had some nuetral saftey switch wires in it that need to be jumped. ill swap in some other relays. its nice having 12 or so parts cars lol. hmmmm. now that you mentioned relays i may have sold one off my car because i diddnt feel like walkin to the backyard and pullin one in the mud. thanks!

[jeff420]

ok, figured id update this for people who search later on. i searched and never could find a definitive answer.

the only difference between the auto and manual harness is an extra plug under the dash and an extra plug that goes into the throttle body. other than that everything is the same and it requires NO modification to use on a original 5 speed car. you just have those 2 plugs that arent used.

i went outside and turned the key over and my fuel pump primed, i think my car was just teaching me a lesson for letting it sit since 8-18-09, the night it got impounded AGAIN lol. it was telling me to stop havin it towed off and not to let it sit so long and not sell parts off it again.
