I have Djet, the first version of the harness, leter 72.

I have the rubber boots on the injector plugs that have two issues.
They are broken
They suck at holding the injectors wires in place.

Can I swap the connector off the end of the later 2.0 liter harness and put it onto the early wiring harness?

By this I mean.
Can I use a little tool to unclip the wires and pull the wires out (with the little metal end in place) and then do the same thing to the 2.0 liter plug end.

Then take the 2.0 liter snap on plug end and insert the wires (with the metal ends in place) into the newer connector ends?

yep.

Cool, I HATE the old style.
I can tell when one comes loose...I pull over and push it back in...runs great again.

Are we talking about the same thing? The connector housings on the 1.7L and 2.0L are identical...no early-late style differences...they should both look like this style. Sorry for the crummy photo its all I have available at the moment.
