Guys you better check some other things.

1. Check your EGR black box oem number. Some have three electrical
contactors and some have five.

2. On both my 83 and 82 they use the little plastic clip at the spedo
head. Both have cables that screw on to the black box.

3. But the 82 has five connectors and the 83 has the three connectors. I
have no idea why but I'll just bet one of them has been replaced before.
