5 Speed Swap Wiring - Plug & play w/ cruise control !!!

[JGood]

I guess I'm just missing the purpose. Is this supposed to be easier? I spliced 2 sets of wires and was done, from what I remember. I connected 2 under the console and 2 under the dash. It could be done in 3-4 minutes. This seems like an all day project with the carpet removal and all...

Or does this add some sort of functionality? I guess it would be a "cleaner" mod, as you aren't splicing, although both splice points are fully hidden...

It does work. this wiring setup came out of a good working order 5 speed car, and keep in mind that i have an airbag car, so to the clutch switches may look a little different.

The funny thing is I could have sworn i would have to wire in a 5 speed harness, but the automatic car has a harness and the 5 speed car does not have a harness since it's "standard".

Basically, remove the whole harness.

the one catch is this.



that black yellow wire that comes from the car (shown in black plug) connects in place of the (automatic's) harness's black wire.

it goes here.




that's it! it sounds odd since i wrote it the way i think, but that's the short of it. As for the two clutch switch plugs, there is one that comes from a large loom of wires from above, and i hooked that up to the top clutch switch, and there is another smaller harness, that runs along the bottom, and i hooked that up to the bottom switch.

You are left with a blue and green wire plug that plugs right into the reverse wiring from the transmission.

ask me questions if you have any.

wait... so does it work?? did you remove the auto harness and add the manual? am i the only one confused by the last post?

[dr.strangelove]

this requires no splicing, and no this and that. you remove the harness, the black yellow that connects to the harness goes into the connector i'll display, and the two switch connectors get hooked up. very simple as far as i can see.

and here are some pictures.


under the instrument cluster (usually under the OBC module box)


blue violet to the green black.


the other clutch switch wired in. probably the neutral switch.


these brown wires go to ground.


one of your clutch sensors capped off.


black yellow to black yellow


under the instrument cluster, just to the left of the steering column.


by the trans, bottom right is the manual hookup

as for that black green wire that goes up by the ecu, its to the left of it. you will see it. it connects to the blue red.

in all reality you can more than likely hook up your clutch switches any way you like, but i remember the location of the switches put them in their spots.

any questions, i'd be happy to answer.

If I ever get around to it, I'll write down what I did. I spliced a wire under the console, removed a relay, spliced the terminals, and have working cruise control. I didn't hook up the clutch switch because I don't use the clutch with the cruise on. And If I do, it's probably because it's an emergency, and I'm going 2 feet in, so the brake switch deactivates it anyway...

I forgot to bring my camera with, but i will make sure to bring it with tomorrow.

Im interested in your results since i have an auto--->5speed and my cruise doesnt work.

[dr.strangelove]

not really wanting to know how to splice the wires by the shifter to accept the 5 speed trans, but rather wondering if anyone else has just removed the entire automatic harness, and then gone with the plug and play method. my reason for doing it this way is because i would like the cruise control function to work.

of course, this harness runs under the carpet 95% of the time so removing the carpet is more or less necessary.

i found that half of the harness runs next to the ecu, and there is one black/green wire that connects to a blue/red wire.

the other half runs under the tach. there is one plug (blue wire) that connects to a blue wire, the brown goes to the ground, a black wire that runs into the plugs to the left of the steering column (specifically the one with the red insert on the white socket, and a black yellow wire that connects to the black yellow wire plug on the harness. There are two relays on the harness, and those are just sitting there. as for the last two white plugs (one for the reverse and one for the neutral switch).

i'm at home now, and i can't remember how those are, but i know that one is capped off and the other connects to something.

will fill that little blank in tomorrow.

at the center near the shifter, there is obviously that large connector that is to the auto shifter, and then if you look a little further you will see the appropriate blue and green wire connector to plug right onto the manual trans.

i'll try to have some photos tomorrow as well to clear it all up if anyone doing a swap is interested.

luckily i have a manual car, and an auto car to do a comparison, but since i'm not done yet, i should have some more info as to the success rate once i'm done.
