    I need to replace the ECU on my 87 Blazer.

    Can someone help me out and tell me where? the ECU is located at.

    Also, Do I need to do anything else when replacing the ECU ?

    Thanks!

    Remove the glove box. The computer is attached to the bottom of the dash, just behind there. /forums/images/graemlins/cool.gif You just unplug the connectors from the old and and plug them into the new one. Be sure to disconnect the battery before you begin.
