Adapting Fuel Injector Harness from 89 smec to work on 92 sbec2?

[zer0321]

I have a 1992 Dodge Daytona IROC originally a V6 but is now getting a 2.5 turbo swapped in- I have the correct computer (SBEC-II) and wiring harness from a '92 2.5 turbo car.

The 2.5 turbo is coming from a donor '89 Chrysler Lebaron (SMEC), of which I have the entire car for parts (engine, trans, wiring, etc).

After getting things mostly swapped, I am now realizing that the Fuel Injector Harness is not compatible. As you can imagine, finding an injector harness for a '92 is nearly impossible...

I would like to adapt the existing '89 harness to work with the '92 SBEC-2 computer...I do not mind using the old SMEC style connectors to make it physically connect, but I need to know what changes need to be made to the harness itself for this to function correctly...

Any advice or diagrams would be greatly appreciated!

You'll need to add two wires from the SBEC because the '89 SMEC stuff had two injector drivers (batch fire) while the turbo SBEC uses four (sequential). That's about it, but I'm not sure if there is room in the SMEC style fuel injector subharness connector for another two circuits.

That doesnt sound too bad if it comes down to it- but does anyone know if I can use a harness from a '90-91 sbec1 2.5 turbo? were they the same in these years?
