Hi all I have an 83’ FJ60 with a Holley Sniper EFI. PO had the LCD screen in the cab disabled / turned off and I can’t figure out how to turn it on.

I’m experiencing stalling issues @ idle after some hard starts. After 15+ mins or so the issue seems to go away.

I’d like to get the screen on to see what everything is set to.

I followed the handheld cable through the firewall and it appears to be connected. But the screen is black.

Answer is pending from PO but figured I’d try my luck here in the meantime.

Thanks!
