i was wondering if anybody can tell me where the ecu is in a 97 3.0cl cuz i wanna run the signal wire to that for my a/f gauge n also what color wire it would need to be connected to thanks

 

underneath the passenger footwell, on the front part............ taake off the floor mat, peel back the carpet and there will be a plate there secured by 4 bolts (2 on top 2 on bottom), the ECU is planted on the botom side of that plate (on the plate)


thats for my 2.2, but im sure the 3.0 is in the same place

 

It's under the passenger footwell

 

im pretty sure that its where u said i took carpet out but didnt have time to look. but i will check tomorrow. . but anybody with a 3.0cl can u verify it plz. do you no which wire is the on that i send the signal to for the 02 sensor i have it all setup but just need to no which wire i connect it to.
thanks bro

 

Bump I have a 3.0 and I verified

 

hey thanks black ack do u no which wire is for the O2 sensor cuz thats the only wir that i have left to connect. i have to run a green wire to that wire on the ecu so i can monitor air and fuel ratio
thanks in advance

 

dont quote me on any of these but all ive got is the diagram for my 2.2 and/or USDM Accord EX, heres the pins that have anything to do with the O2 sensors and their tags:

PIN# = WIRE COLOR = TAG = meaning (that I can gather)

pin A5 = Orange/Blue or Orange/Black = SO2SHTC = Downdraft (Secondary) O2 sensor, im thinking this might be an output lead

Pin A6 = Orange/Black = PO2SHTC = Predraft (Primary) O2 sensor im also assuming this is an output lead

Pin D7 = White/Red = PHO2S = Perdraft O2, might be a signal for the ECU

Pin D13 = Green/Blue or Red/White = SHO2SG = downdraft O2, possibly a ground pin for the "G"

Pin D14 = White/Red = SHO2S = Downdraft O2, possibly the input wire for the downdraft (difference between G and no G???)




afraid thats all ive got, but it should be a ballpark idea of whats going on
