What will happen if I remove my ECM???

Took the L98 out of my 89 Formula and have a Ram Jet 350 to go back in. The FJ 350 has its own computer and harness, so can I remove the L98 ECM as long as I leave all the wires in the car that go to the Lights, blinkers, speedo, tach, etc?

i.e. (will everyhting else work right if I take that computer out?)

------------------
L98, 3.27 9-bolt, Hooker shorty headers, custom 2.5inch Y-pipe, no cat, 3inch 2chamber flowmaster, JET AFPR, Ported MAF, Best ET: 13.86 @100mph. 1.99 60'
17 inch ROH "ZS" wheels. 17x8.5(front) and 17x9.5 (rear). Firestone Firehawk SZ50s. 245/45/zr17s and 275/40/zr17s. T56

On the way... Radar Blue 89 Formula, T56, Ram Jet 430, Ram Air, 17inch ROHs.

The only other thing that would be affected is the torque converter lockup clutch. As long as the new ECM has the connection for that, everything will be the same. The ECM has nothing to do with lights, gauges, etc.
