I have a 92 lx hatch had a 2.3 motor and automatic transmission I've read it could be possible the 2.3 automatic could have 373 gears is this true and also I have a 5.0 ecm from a 89 gt and a 5 speed tranny in the car now with a motor from a 99 explorer put a rpm intake and 650 holley on it I have a efi dizzy in it and try to see if I can use the 2.3 wiring harness to power the efi coil and dizzy I've had the same setup before in my 87 t top gt just without the 2.3 harness it had the gt harness and ecm but I tied the harness back and all I have was a 6al msd box with efi dizzy and coil from factory please help

Welcome to the site, but you may want to start a new thread in the Fox/SN tech section for this. You'll get more responses. I don't think you can use the 2.3 harness, but I'm just going off memory from another post awhile back. Also, your post is alittle confusing to follow, try to simplify your questions and state what is not working on that harness. Good luck.

You could also use the search feature, I know there were a couple threads with this exact question.

You may want to upgrade that rearend also, it may have better gearing, but it's the weaker 7.5 carrier. Grab an 8.8 from a 5.0 fox.

If all else fails jack up the rear end and count drive shaft rotations vs. wheel turns.

If the drive shaft turns 3 1/2 times per one tire turn it's 3.55 and if it turns 3 3/4 times per tire turn it is 3.73.

Place a mark on the drive shaft to help you count rotations.
