switching an "idiot light"??
 

looking at going with a MS2 v3.0 diy kit and am wondering if i can retain my over rev/ over boost light i have in my gauge cluster that i had running from my emanage blue setup.

this is what i was thinking. ONE LED...multiple conditions to turn it on..

1)Rev limit
2) Over boost
3 Oil temperature too high.

1+2 are must haves, but the oil over temp is something i thought would be cool too. use a GM coolant temp sensor or similar as an input into the Ms2 to trigger the light?

Why do you need those in your gauge cluster?

Rev limiter will soft cut, then hard cut on MS2.
It also has overboost protection.

MS2 can use the first two conditions OR'd together for a light.
