1989 Spider Wiring Diagram, Motronic


Does anybody have a wiring diagram for the 1989 Spider? The 1989 spider is a rare bird, in that it has a series 3 body, but a series 4 engine. That was the last year for the series 3 bodystyle, but the cars came with the motronic engine, that the later Series 4 cars (1990 - 94) had.

This seems to be Alfa's procedure. They don't do a chassis switch and an engine switch in the same year. The new engine gets a one year tryout, before the chassis/body changes.

If you have this diagram, can you PM me, and I'll send you my email address.
I think the moderators don't want files posted to threads, so much. They are concerned about copyrighted material being posted onto the board, which is then possibly their problem.

Thanks in advance

If you have a series three body and Motronic it is a 1990 model in the US. Yes it has a one year only wiring diagram. I have 1989 April build with L-Jetronic, never seen one with motronic. It would be a lot of work to change over.

Papajam, the guru who makes the diagrams and holds copyright on them sadly passed away recently. Other moderators are working with his widow to possibly release them so Jim can live on helping us with our electrical woes as he has done so gladly in the past.
