TIII swap

[Millerman340]

There is a 92 IROC Daytona for sale in my area, It has a 3.0 v6 & a auto trans. I had a idea of swapping in a TIII engine & trans for a poor man's IROC R/T. Would it easier to find a 4 cyl harness or will the spirit R/T harness fit the Daytona. How about re pinning the v6 harness to mimic a TIII Daytona harness & sending the computer in to Cindy to re cal..? Any thoughts?

I would start with the V6 main harness and use the Spirit R/T negative sub and injector harnesses. You will have to cut and splice a few but if you have the 92 wiring diagrams in front of you its not that hard. The hardest thing will be finding a 92-93 TIII SBEC to run it after you are done. A 91 will work with a few more wire mods but if you already have one of them and are cutting on the harness setting it up for the 91 is easy too.....
