so I did some research, found out that I need to find a yellow/red and a green/blk wire in the console and cut them and run new wires to the transmission. I found the transmission sensor, cut the 2 wires and ran the 2 wires to the centre console. But now I couldn't find those 2 wires in the centre console that I'm suppose to splice them with... I don't know if anyone could help me out with this. I did some research but they were all honda civic harness. I found the connector that was for the auto shifter but it has more wires. I found a green/blk one but only a yellow/silver one.
Also, I found out that a auto ecu Vs' a manual ecu can be the cause of my rpm jumping non stop from 1200 to 800... Anyone would know about this? and what I should look for? apparently it's something to do with switching a wire in the ecu from 13 to 14... any help on this would be great too.

The reverse lamp one is kind of a rush for me to be able to get my safety for my car to change the ownership

why didn't you just get a manual car to start with

What engine / tranny combination are you running?

Nice.

alright so after A LOT of searching and reading tons and tons of electrical diagrams, I figured it out. I'll hope my explaining will help others that also would like or already did auto to manual conversion.
First come first, the tools needed,
-phillip screwdriver
-electrical cutters or a knife
-some of those connector things that locks 2 wires together I cant remember the name or simply a few twist and electrical tape, whatever you feel more comfortable with.
Some electrical wire, about maybe 4 meter, give/takeSo what you need to do is locate the connectors, if you are in the process of doing the swap it will be even easier.
The first thing to locate is the sensor on the tranny. it's 2 wires, If I remember they are both grn/blk. then you need to take the center console apart (if its not apart already lol) and you need to locate the pin that used to be attach to the auto shifter. (their should be 2 of them, one is 3 pins I think which is also important for something else and the other one is a 12 pins. Should be something like this
[ 1 ][ 2 ][ 3 ][xxxxxx ][ 4 ][ 5 ]
[ 6 ][ 7 ][ 8 ][ 9 ][10 ][11][12 ]
I found different diagrams on different prelude manuals, but overall they were all pretty much the same thing.
the one to focus on is the No# 9 and 10 which is the current and the power that goes to the rear back-up lights.
this is what you need to do:
Cut both wires on the sensor attached to your tranny, leave about 5 inchs to play with. then take the electrical wire, make 2 long wires, connect each wires to the 2 wires from the sensor.
Then run those 2 extended wires all the way from the engine bay, trough the firewall and all the way to the center console where the 12 pins plug is located. Then, cut the wire 9 and 10 giving you enough wire to play with. the 2 wires should be grn/blk and the other one is yellow, they are right next to each other so that should make it easy. connect those 2 wires to the 2 new wires you just ran trough the firewall.
seal everything, and voila, now, you have back-up lights working everytime you put your car transmission in reverse.
I'm sure there is other home made ways to get around this, but this is the right way to do it. Clean and as close to factory as it gets.
Hope this helps, if anyone needs more info, feel free to add it here or IM me.
(My next mission, to succesfully connect the cruise control)

Lets see, first, auto cars are generally in better condition overall since they are not driven the piss out by young punks who can't figure out how a car works enough to keep it healthy.
I came across a car that was in immaculate condition for a very reasonable price. The most expensive repairs, like rust for example, this car has none, and the car already had the manual conversion done, but the guy who swapped it did a half ass job, so his lost is my gain.

hey did you change the ecu? yet ? pm me id liek to alk to you more about this becasue were doing the exact same project

jeunefred

I haven't got to the ECU part yet. I'm still trying to find out how to identify a P13 vs other ecu. Theirs a possibility that the ecu on there is for the h23 and not the p13. since the car came with a vafc.
I also found out from another website that you have to change a pin from something like the 13 to the 14. I have to look into it more, apparently it could be a cause for a ruff idle. (Which I have right now)

I just bought the car and I still have a lot to find out, (The car was converted already but with a half ass job)

If the ECU still has all the stickers on it, its easy to find. There's a few numbers then ' - P13 - ' and more numbers or something like that.

Hey thanks! I'll look into that this afternoon

Since I can't search for pin 13/14 swap, what does this do exactly? Have you found your answers for the ECU swap?
