1988 L98 Trans Am to 1991 RS TBI Swap

Hi guys, I have complete 1988 L98 engine, wiring and ECM from Trans Am and have a plan to put in my 1991 RS 5.0l TBI Camaro.

What is the best way to keep speedo working?

1988 Trans am has mechanical speedo, 1991 Camaro has electrical speedo, so it won't work after swap.

Is Dakota Digital Speedometer and Tachometer Signal Interface only way to solve this problem?

Thanks a lot in advance.
