Here's a little something for the 3.2 Motronic conversion projects out there.

A complete wiring diagram to adapt a factory /6 to a 3.2 Motronic. If you want to use it on a /4 chassis, you can by moving some of the pins in the connector to the harness. This also eliminates the relay board, and adds a fuse box for the Motronic.

I know this harness will work, I built it for a 3.2 engine in a factory six. Everything works, including the temp gauge in the dash, the charge light, and the oil pressure light.

I intend to redraw the diagram for the /4 chassis, but I have not finished it yet.

Oh.. and I drove the six with the 3.2 on Saturday.. a euro spec 3.2 that has been chipped....

WOW... Man is this beast FAST!! Blink and its a redline in first!

I should have never driven it.. Now I want one!!



I may be able to get my hands on a complete 3.2 with a spun rod bearing cheap.....

That'd be just the trick I need in the 4 flavour...looking forward to the post.

Thanks Clay!

Um, both the coil wires are part of the Motronic harness. (at least on an 84, 86, and 87 engines).

There have been a couple of posts that have 3.2 pinouts between the engine and 914/4 harnesses. (if one were to search.....)


It is a cute picture though.

You should check out this thread for 3.2 conversions

The 3.2 conversion thread

and here is a pic for the pinouts between the 914/4 harness and the 3.2 engine harness.

I know both coil wires are part of the harness, but you have to hook pin 15 on the coil to switched power to get it to run. This adds a fuse like the factory did it on the 911.

Clay: Hmmmmmmmmmm......You get the 3.2, and I'll take that "old" 2.4L off your hands.

Here is mine....

Ok.. but you have to buy an oil tank, lines, motor mount, throttle linkage....etc...

The engine is the easy part.
