90-92 TBI harness vs 90-92 TPI harness

How differnt are they? Like the ECM connector and what not. From what I can tell since they are both SD they are basically the same except for the injector connectors

Only reasont why I ask is because I am gonna swap in a 350 TPI outta 89 GTA into my car. If I can just mod the exsisting harness I'd do that instead of modding the MAF harness for SD.

Thanks

The later ecm uses 3 connectors where your's is 2. There is a fair amount of repinning of the connectors. If you go to the DIY Prom board and search under Mike Davis there are some links to his site, and he covers it in detail how to change thigns over.
