ok as im swapping engines out,i need to swap ecu's, now ive taken the bottom one out,but i cant seem to get the top one out? the 2 scews on each side of it are for the other one i have removed. cant seem to get my hand in and around it? anyone else removed one like this before?is it connected on the other side.i dont want to pull on the ecu hard,just in case i do damage?ive taken 2 screws 1 each side at the top off. it wiggles around but wont come out?
