HEI control ESC

[peter paul fenske]

HI Gang

I think the truck LE9 engine uses this system.

I have the sch of the system not the esc box in
the canadian supplement.
If people desire can scan this

I think similiar systems were used in pontiac 301 4bbl
god rest in peace engines and few other gm marks

Yep you can use HEI module whereever you have a mag pu
works great in fords and chyslers
