Out of everyone here who's done a 4g63 swap nobody can confirm if they used the dsm or csm mpi?

If it plugs in and works then don't worry about it. They aren't expensive. Find a dsm one just in case.

Look up any of the wiring diagrams on my site. Find the MPI relay page. Print out both side by side. Compare.

Thank you. Well hopefully I'll be doing a first start today I'm trying to get this done before the rain hits (a week or less). That's why I'm trying to sort out all my unforeseen issues before I get to them. As of right now the stock turbo csm mpi relay, power transistor, coil and resistor pack are being used.

Mine is running stock relay. 91+ motor . All I changed over was the coil and power transistor for a 90. The TB was whatever I had in my parts bin. I threw in an old used 14b. Cranked it over and hoped for the best!
I had no motor in my colt when I got it and I had to sort out the hacked wiring harness in the engine bay. I had no idea what connector did what.
In the end. It all works out.
One piece at a time.
