swapped in a new motor and trans with the harness and i have run into a few issues. the major one being this. is there a difference in transmissions for the auto and manual one? my car used to be an auto and i dont know if the placement of that hole for the shifter to go through would be in a different spot or at least shaped different. but then that wouldnt make sense.......**** man idk.... the other issue is the white plug off the new harness next to the ecu doesnt match up with the plug in my car. is there a fix for this? is this because the harness off the new harness is newer/older than the one in my car? this is the one from my old harness this is the new i also grabbed the fuel pump out of the donor car and it was wired up like this. is this just the standard fuel pump rewire? also i am looking for a diagram on how to install an msd 6a. i found this diagram but i dont really understand it. not the words, but the locations for the wires.

Have you EVEN SEARCHED the FAQ section for info on the AUTO to MANUAL swap?

cr-rex

i have. everyone says the same thing... it "bolts rite up".. disregard the auto to manual swap part. the swap was done YEARS ago. the trans i had in there before this one mounted fine. now i go over to the SAME transmission from a different car and it mounts like this.

i dont understand why from the ENTIRE post the only thing you had to say is "did you search". what kind of input is that?

just for future people that may have some sort of useful input on this,
`the ppf mounts perfectly to the trans when it is in that postion.
`someone told me it could be either the motor mounts or the subframe causing this issue. its a little confusing because if that were the case then wouldnt the ppf be off as well?
`the motor mounts that came with the motor are solid mounts. the way that the previous owner had them in his car was with no bracket. just the mount and the little ear off the motor. the only thing holding the mount to the motor and the subframe was the bolt. it mounted perfectly in the other car that way so i didnt want to mess with it. would putting the bracket on the mount make a difference? i'm worried that if i get the shifter part to sit where its supposed to then the ppf wont mate with the trans and i'll be back to square one...
they look like this

Your supposed to use the brackets.

If the manual trans is not lining up you have somehow managed to install either the engine or trans incorrectly. My best guess is you do not have the engine mounts installed correctly causing the engine to be twisted or angled in the engine bay. Are you sure the motor mounts are installed and seated in the subframe correctly?

The PPF will not line everything up for you perfectly. With just a trans installed you can physically move the trans from side to side with it attached to the PPF. Once again I think your problem lies with the motor mounts.

Yes, pretty standary, but that looks pretty ghetto. You should clean it up like this: http://www.rx7club.com/showpost.php?...&postcount=173

Here's the diagram:


Ideally you want to make sure you have 10gauge wire inside the tank as well (from the pump itself to the connector at the top of the bulkhead).

thats what i figured but since the previous owner didnt have them, i didnt want to change anything. i'll put them in though...

i will double check the mounts after i put the brackets on. i didnt think the mounts could go any other way since the hole for the bolt will only allow it to mount up one way. but i guess not...

i will double check...
thank you, your the man. i didnt know there was a difference. i figured the harness that has been in the car this whole time was a manual harness since whoever did the swap a long time ago. but this should fix me up after i try and fix the fitment issue then i will be good to try and fire this thing up.

Some of the conversions are done poor mans style and they just modify what they need to.

all issues solved. i am keeping the fuel pump wired the stock way for now until i look into the rewire a little bit more. the white plug, x14 i believe, have been repinned according to the write up so thats good. the trans not lining up... the cause was motor mounts.

i pulled the motor BACK out and mounted JUST the trans to the ppf, leaving the nuts loose to slide it forward and back as need, THEN put the motor in. its very tricky to mate the motor with the trans than it is to mate the trans with the motor.

but either way, the **** lines up. its off slightly but not enough to cause any kind of interference.

thank you everyone for your help... everyone except RENESISFD. youve helped before but this time your post was worthless.

RENESISFD

Why was it worthless?


I told you where to look for the answer to most of your questions.

cr-rex

read that to yourself........





now read my original post. HOW in ANY way, shape or form, does that help me with ANYTHING in my original post.


a way it would have been helpful:
"hey the plugs are different from auto to manual. maybe you missed it, look here {insert link}."

or

"hey, your car was ALREADY MANUAL before you started the swap but it looks like they kept the auto harness. check this out {insert link}."

what theorie did was helpful. he basically spoon-fed me the EXACT information i needed but i would rather have it way then find what i think is the correct information and have it be wrong.

now please, tell me how i'm wrong..... ready? GO!

What was the tricky part of mateing the motor with the tranny? I'm about to install my motor and any tips would be great.

cr-rex

i dont know about other people but my tranny hung a little low for the motor to mate with it. it was hanging below the subframe. i had to use a jack to lift the tranny and lower the motor into it. the tricky part is that since i was lifting the tranny, it would sit at an angle like this / or like this \. so i would have to lower or raise the jack until it sat like |. you understand? all while getting the motor to slam into the shaft that goes into the clutch. make sure you leave the ppf nuts that hold the tranny to the ppf loose so it can slide forward and backward on the ppf.

when you get it in, you have to hold it there because it has the tendency to swing forward and un-mate itself from the tranny. while holding it with one hand, you have to reach down and thread one of the tranny bolts so the motor doesnt swing out.

the only reason why i had this problem, is because my motor mounts were not attached to my motor like they normally are. i had to sit the motor down on top of the mounts that were just sitting in the subframe. so they would slide around and stuff like that while dropping the motor. also, i was by myself.

let me know if you have anymore questions. if your using stock mounts or your mounts are attached to the motor then it would be easier to mate the tranny with the motor instead of the other way around i think. it was easier for me that way when i did my second motor...
