how do i replace the tcu in my 92 accord ex

 

this is just a guess, but I'd imagine that you pull the plugs out, unbolt the unit, replace it with the new one and plug it in.

 

i understand that, but where is it located. my manual dosen'tshow it.

 

rt side, inside the car ,at passanger feet under the carpet ,, the TCU is the 1 on the right side,, the 1 on the left is the ECU
I believe that there are 4 , 10 mm bolts, unplug the connectors, both ECU and TCU will come in the craddle,flip it upside down, then remove the remaing bolts from underneath and remove the TCU ,, pretty easy job ..
