1994 Evinrude 120hp + System check controls

[mykal41]

Good Morning... I have a 94 Evinrude 120hp going on my 17' Osprey. While shopping for controls I found a
good deal on the system check top mount. I have all non system check gauges already. Can I use these
controls?

I tried to find info on the "system check" controls and couldn't find any

There is no "system check control". There is a system check main harness that is nothing more than your standard red plug omc harness with connectors on the ignition switch end instead of ring terminals for a ignition switch.
