Chrome ECU equivalent???
From the 1989 catalog, theis is the MP p-part number.
From the ''Speed Secrets" version of the bulletin
it could be used with the 3 'chrome' boxes with part numbers listed next to the check in the footnotes.
Any resistor from .5 to .8 ohms was acceptable, but .8 was prefered.
If you can't find a p/n on it, then you have to try to go by the heat sink, and how it was used. Two had blue.
The Superstock/Nascar unit will be hard to find.
Only the p4120505 from the '89 catalog was suitable for street use - the heat sink was different.
edit: Somewhere around '89 I suspect the 0505 'chrome boxes' were painted orange as we cansee in the catalog photo,
I had a chrome ECU purchased around then, and it was chrome. Doubt I still have it to see what color the heat sink was.
The tables can be a little confusing but there are several that will work with the big yellow super coil.
