Title: Under the Dash
Post by: rockable on March 01, 2009, 01:22:28 pm

Is there a gaphic somewhere that shows what the ECM looks like and where it is located on my '86 305?  Also, where is the cruise control module and what does it look like?  I'm looking at a bunch of stuff under my dash but I can't figure out what it is. 

Thanks, I'm trying to get my cruise control working.  It's one of the last things on my punch list.

Thanks, Vile.  I'm sure I can find the cruise module now. 

I'm relatively certain that my truck has no ECM since it has no Oxygen Sensor, Spark Control or other electronic stuff.  It's just got a potload of vacuum lines with all sorts of vacuum switches, solenoids, etc.

If it does, you would find it behind your glove box, above the AC blend door area.

Here's what mine looked like (before I ripped it out):

Well, I sure hadn't looked there.  I'll sneak a peak.  Thanks!
