so i have a 01 itr that was stripped and im turnign it into a strip car im almost done but i have 1 question the vehicle had NO wiring in it so i built my own harness just for the things i needed cause its a dedicated track car. question is How do i wire my clutch switch to the ecu so i would be able to utilize my anti-lag and stuff like that?? ive tried researching and looking at diagrams but nothing usefull has come up. any help would be great suppost to be going to get tuned this week in prep for honda day!

 

Depends on what you use to turn it on/off. There are two types of switches, one that is on when released and one that is off when released. Check your switch and see what you have.

The way I used mine is one side of switch to ground and other side to ecu.

yeah thats what i figured but i cant find which pin in the ecu to go to im using an obd1 aem ems

 

Check your software help file. Hondata lists available inputs and whether they are 12v or ground. I'm sure AEM does the same.

 

I'm using the factory clutch switch that's in the integra

 

You can use any available switched input on the AEM, you just have to set it up in the software to which input you end up wiring it to

 

Ohhh ok um 1 more question does anybody have a pinout for the switched input on a v1 obd1 Aem?

 

Yes AEM does, download it from their website.

If you install the software, you get install instructions on basically every box (includes a Pinot in the instructions)

 

Ok thank you!!!

 

Sorry if I'm threadjacking, but I have a similar question....

is the stock switch a ground in - ground out (to ecu) from the factory?

 

I could be wrong, but I believe it's continuous when the clutch is pressed down...

The best part is that it doesn't really matter, you can set it up for either type in AEM and most quality EMS (normally closed vs normally open)

 

I see. Thanks.

Hopefully neptune rtp has a function like that. lol

 

So the switch is a 12v circuit.... How would I wire that? I have it go to a switched power in the ems but where would the other wire out of the switch go?

 

Still don't know how to do this lol

 

Ground one side of clutch switch wire and the other wire goes to ecu. That's how I did mine. I also used the other switch above clutch switch for my boost controller using 12v.

 

Yeah I get that but I can't find online where to wire it to an obd1 Aem

 

Aem Power forums look up the wiring diagram for a obd1.

 

what ems? i dont even use a switch i just set it to engage under 1mph. much simpler.

 

Its a version 1...... I found the pinout for the ems but my harness doesn't plug into that part which is plug c.. Do u just pin 1 wire to that empty slot? There is no plug at all

 

usually its pin b7

thats what my 92 cx was wired to from factory and ectune had an option for it and it worked great

and how i did it on my 95 cx hatch that wasnt wired in... i ran a wire from ecu, pin b7 to the clutch switch, then on the other side of the clutch switch i ran that directly to ground ...

i also like to use the cruise control switches... there will be 2 of them on ej1 and eh3 cars with cruise control it will be the lower one, that switch has a released ground so when you push the pedal it grounds the circuit.... the higher switch is the neutral safety so the clutch has to be pushed in to start the car...

you can use that switch that is a type of switch that is normally not connected when released and connected when pushed... i dont like that style i havent figured it out how to use them i know with ectune and hondata and aem im sure you can, but its just alot easier to use the cruise control clutch switch

 

also with using the spot on the clutch bracket where the cruise control switch goes, it cuts as soon as you push the pedal...

if you use the higher spot for the clutch switch the pedal has to be on the floor to operate... wouldnt work to great imo and i never use that spot i always use the lower spot
