i was wondering if any of you guys that have done this 2.3 to 5.0 swap have used just the wiring harness for the motor or if you had to use both halves?
i have also heard that the 5.0 gauge cluster will not work with the 4cyl harness.
this is my first fox project so any advice, tips, or tricks would be much appreciated!

You can use just the engine harness if it is from the correct year, and the 5.0 gauge cluster should work with the 4 banger harness.

Most people I know use the 4 banger cluster, only difference is that the rpms are doubled on the tach.

Check the sticky on the top of the first page. It includes a link to a post all about 4 cylinder to 5.0L swaps. There has been much discussion about this topic, so doing a search should provide you with more info than you can imagine.

I did the swap on my 91LX. I used a engine harness out of a V-8 91 and a A9P computer. My stock 4 banger gauges worked fine, with the tack reading double. I later on swaped it out for a V-8 cluster and all the gauges along with the tack read perfect.
