Electronic schematics need for 87 LM and 88 SMEC

[chromguy]

I cannot locate the Electronic schematics for 87 LM T1 and 88 SMEC T2 , tried our friend google, no luck.
I really do not want to reverse engineer the beast
Thanks for your help.

Take the space out.

Thnak you tryingbe, I have combed Russ' site in the past but no luck. I have the complete service manuals for 87 and 88 on hand as well
The electronic schematics shows how each component is connected to each other on the PCB board in the inside of the ECU. It is not contained in the manuals.
They typically look like the following

Chrysler has always considered their ECU designs proprietary and therefore have never released circuit board design, componentry listing, or circuit diagrams for any of them.

Virtually everything we currently know about them has come through reverse engineering.

Thanks Barry,
Do you know anyone who may be willing to share their reversed engineering efforts?
Also anyone have any suggestions for "on the workbench" tests? For example, hook up 12v and grounds to various power points. Apply x volts to various sensors and watch the injectors and spark timing on waveforms on my oscilloscope. Sure I can figure all this out but why reinvent the wheel as they say.

Someone built a SMECStim a few years ago. I have one, but have never really used it.

A good portion of the LM schematics are actually available in one of the Chrysler tech training books. It's missing values, but there are docs out there with the values added. I think Una (perma banned just about everywhere) posted them on Turbododge a while back.

Thanks Shelgame,
I searched google for hours but no luck. I seen when the moderator removed items from Una's posts. I will give another search soon.
