I'm going to be putting a jdm cluster into my sol when it gets here for the higher 8.2k tach to go with my gsr swap. My question is regarding the additional indicator light found in the tach cluster. I've been told that this light is related to a stock egt sensor?? IF this is true, how would I get this light to function in a usdm sol with a 94 b18c1 swap? Was this light driven by the ecu or does it function more like the batt and oil pressure idiot lights?? Is there a jdm p72 ecu what would work with it? Parts info would be greatly appreciated. I'll take even a better explination of what the lights function is.

Thanks

 

bump for night

 

there must be someone who knows something about this.
