Installing 1989 N/A 2.3l and A4LD into 1948 English Standard and planning on using stock ECM but donor original Mustang wiring harness is a mess. Looking for diagram if anyone has one or can help. Thanks in advance for any info.

If you go to autozone.com and register...free.. they have the diagrams up to '88...should be the same.

Welcome Second source. http://www.rothfam.com/svo/reference/88-90Mustang.pdf Cool project. Putting a 2.3 turbo in a MGB. Already did that to a 89 Mustang. Good luck and post pictures. If they won't let you because of not being a Mustang PM me and you can e-mail. Love the idea. Maurice

Cool swap! Have you considered going turbo?

This is what I use. It's the real deal!

Pin out at dash.

Now for the engine fan. A few choice. One is a aftermarket hotrod fan controller. Numberous suppliers have them.
Second is use the factory. Just unplug the AC section and it will work just like have the ac off. Now if yours is messed up.
Early model Mustangs use a trw module under the dash at the gauge console. What it looks like a picture of usual failure and my method it fix.
