I just finished my h22 swap into a 94 honda accord ex. now for some reason the ecu isnt grounded. where are the ground points to the ecu. all the engine grounds are placed and tight. SO my question is where are the ecu grounds located at. it has 12v but no ground. thanks for your help in advance.

 

You could just ground it anywhere could you not?

 

yes thats what i did to get the motor tarted but i would like to know where are the stock ground location for the ecu so that i could check and see what the deal is.

Is it in the main relay? thanks in advance.

 

any one?

 

just for future refrence. the ECU ground point is at the intake manifold next to the master cylinder on the vacuum block.

 

are you sure the ecu ground isn't the one on the thermostat housing?
