Unfortunately I don't have any kind of manual. I think pin 87 is a ground, I don't really remember. If it is, and there is a place for this extra pin that has no juice, I think it might work. I'll have to check on mine to see just what pin 87 does.

$$$$ is really tight right now, so that's why I don't just buy a new one. also the 1982 380 sec this came off of might be my son's next car, as his got totaled. the only thing is that it sat for a year, has half a tank of bad gas, but it will run if you keep spraying carb cleaner into it. Probably needs to have the fuel tank cleaned, possibly a new fuel pump, but that is another story/project!!
