Well, as I'm assembling my project I'm finding out what is and is not here. First thing I realized was I have no coil or the mount. Can somebody show me a picture of where that is located on a 1989 4.3? Also, I know one leg of this is broken and it bolts to the intake manifold but what does it do? Guess I'm going to the junk yard soon.
no the coil from the factory is mounted with its own bracket. it sits right behind the throttle body assembly. The item you showed is for the map sensor and another sensor I can't find the name of. The bracket has been cut so grab the bracket from another 4.3 in the junk yard. My advice is find another Astro the same year and engine and take a few pictures to guide you. Anytime I work on another vehicle I am not familiar with I take pictures prior to starting and store them on an external hard drive for future reference.

That bracket holds the ESC module (at the top with the exposed terminals) and the map sensor (on the bottom). Here's a crappy pic of it (and location) on my 88 Astro. Sorry about the mess, but I was getting ready to pull the engine, and didn't have a better pic (I looked).
It's located just forward and to the right of the distributor.
This part assembly was used from 1986 thru 92, maybe thru 95 on the TBI engines, and also could be found on S-10's and S-15's with TBI.
I hope this helps.
Note, it's actually located just in front of the coil, and is under that wire cluster mess. It gets bolted to the intake manifold stud and a bolt hole in the manifold, which is probably why yours was trimmed off.
So, can anybody post a picture of the actual coil and it's mount? I went to Pull-A-Part yesterday only to get the wrong part. This was off a 4.3 ZR-2 S-10. Anybody need this?
Best pic I have is for my '91, I guess I've never really took one of just the coil and/or mount.
Mine is mounted between the dizzy and the TBI. Ignore the breather hose that looks like it's attached to it. Two black plugs on one side, and a tower on the other for the plug wire (to dizzy center).
So is the Astro bracket different from the Blazer/Jimmy/Bravada mount? The pics I posted were from my '93 Bravada and the replacement engine for my '93 Astro, but it came from a '94 Blazer.
Just to clarify he said his is an 89 so he has a TBI engine not CPI. I will take a picture of mine tomorrow , yes I have a 350 but all the brackets are from my original TBI 4.3.
So, I found the piece that has broken of this bracket. Is it possible that the missing piece attaches at a 90 degree angle? I do have an aftermarket intake manifold, but I don't really see a way that it fits like that.
h=go to a hardware store or home depot grab some steel stock it comes in many sizes and make a bracket to mount it. Just drill the holes in the broken bracket and bolt the home made part to the existing bracket.
