So not boost about myself.lol but I didn't this for the first time back in 2000, so yeah its been done before my brother did it in 92 with a ef and many many people didn't it the min the car rolled off the lot. It's super simple if you search for dpfi to mpfi swap. For ANY EF CAR IT IS ALWAYS THE SAME the 90 is JUST LIKE a 89 or other models. Very very easy just add some wires intake nano complete! And module dizzy and wabam! Better the Emrall cooking.

Its nothing. Literally. Take the yellow and black wires and solder them all together with the other 2 coming from the ECU. the "power block" is just 12V power from the ECU.

I just did this swap last week. I followed that guide exactly and I had Zero problems. Started right up. I even did OBD1 swap at the same time. If you have any questions just ask. Its super easy if your decent at wiring.
