I Know i'm most likely going to get blasted, but i have a hynes manual, and i cant find where the ecu is located..plz dont kill me lol

 

1992 vg by the way

 

behind the radio

 

so i only have to take out the radio to get at it...or is there a way to get behind there through the side??? thanks

 

it's to the right of the gas pedal.
you're looking at the lower metal box w/ the big wire loom going to it.

 

well i'm trying to hook up a a/f ratio gauge...how do i find which wire i need to tie into??...thanks guys

 

my question is related. how does one get to the bolts on the back side to take out the ecu? i bought a used jwt ecu from someone and i am having trouble removing the two bolts at the back holding the ecu in. there is hardly any clearance back there to get a screwdriver or ratchet back there. Is that the only way to take the ecu out? Or Is there an easier way to go about taking out the ecu to replace it? Thanks.

 

oh boy a/f gauge huh.yeah you really need to now that on a stock motor. Ok man if you could send it back to get another type gauge do it know. I would much rather beable to tell what temperture my oil is or pressure is than watching a disgo ball flashing. I had to find that out the hard way. Mine for some reason flashes to the music..huhh great! So im going to be throwing that bad boy away and going with the wide band. Ok if you must have it this is how you can hook it up. run the signal wire from the gauge to the o2 sensor Their are three wires at the sensor You want to hook it to the black wire it is the signal wire.

 

thanks...i like the disco lol

 

ok i found the 3 wires...ones black ones white and ones red...so i want to tie into the black on correct??? thanks for the help

 

I thought it was the white one

 

thats what i thought too, silverlinekenne said black...i just wanted to make sure

 

whatever you do...don't cut the red one the internal ECU bomb will go off!

 

but it is the black one right?

 

is there any other wires for an air/fuel gauge that you need to hook up besides the o2 wire?
