Ignition Control Module Installation Question

[challen66]

Trying to install a new rear Ignition Control on the Olds 4.0. There is a sensor attached right in the middle of the ICM. I got the front two screws off and the back / top screw but it seems like it's attached to a flex hose in the back.

Anyone know how to get this off so I can get to the ICM?

It will take a small gearwrench and a few swear words. Tight fit, but can be reached from underneath. Just did this a couple months ago.
FYI ~ Not sure what tool in your shop is your favorite tool, but the GM Shop Manuals are my favorite tools.

I hated that Job cause it's frustrating. When I was done with job I never installed that Black Bracket again.
If I remember there are 2 more Bolts or Nuts (10mm) behind the Head of that bracket and that Valve attached to the Flex Hose there are 2 more 10mm Nuts underneath the Valve.
I used a 10mm Rachet close end Wrench. This Job is going to take some time.

Thank you both for your help. I got everything off from the front side but was trying to avoid coming up from the underneath side of the block. At least the bright side is I have practice with the front so it shouldn't take too long.
