went to plug my ECU up in my 97 Civic with a ITR swap using a 99-00 Si engine harness. i got a OBD2B to OBD2A jumper cause the ECU is OBD2A. i was scratching my head cause i plugged everything up and had one spot left one the jumper that was pinned, but no plug to put in it. i searched tonight and found this........

let me guess, it is a brown plug? because when I did my dash swap, I left the Si harness on the dash and I think I have an extra plug(Brown) I am not sure what it goes to. I haven't had the chance to really mess with it, and my pass. window doesn't roll up to top it off. Lucky my car is in a garage!!!!

BUMP, cuz I am curious to know what the plug is for. I just figured it was for the OBD2 readers to plug into and read the check engine lights(CELs). Who knows...

the OBD2 reader plug is the little blue plug, the one circled in this picture.

 

????anyone????

 

that blue plug is for checking your CEL(i think)...my is blue and others are prolly brown, you cross the two wire and start the car and your CEL blinks...

Yeah, I know how to read the codes(I knew it was the blue plug(little one)) but I have a big brown one left over and figured that was the same color of the plug you can't find where to put it. After looking at your pic, It looks like the brown plug is to a relay of somesort(in my situation).

Anyways BUMP, for the orginal question!!!!!!

Sorry I might not understand what exactly what you're saying or asking. Are you saying that there is a hole for an plug on your OBD2b to OBD2a conversion harness, and that there isn't an extra plug (from the Si harness) to plug into it? If I read that right, is it a smaller one on the end (D)? If it is, then that's a slot for an automatic motor and wouldn't be used when using a 5-speed. I'm sorry if that's not what you mean, I'm just not sure what you're asking.

so my question is.......... is the information stated above correct? do i have to use the 96-98 harness or can i still use the 99-00 Si harness in any way? what are my options?

 

Dont use a 99-00 harness in a 96-98 car. Heard it's a bitch.
Stay with your own year. Use a 96-98 harness to save time/hassle/trouble.

this confirmed the above statement of, the 99-00 Si engine harness not to be plug and play with a 96-98 Civic.

thanks for the info, confirmation of this.

 

now looking for a 96-98 engine harness. would like to get a EX but will use others if the price is good.

 

i have a 97 harness non vtec
