mtsinner7868 Posted October 18, 2013 Share Posted October 18, 2013 Hello all. Picked up an 88 turbo 4x4 wagon........ I need a little help with the dash turbo light(s). There is the turbo light itself (I assume) and a square light around it. What do each represent ? Sometimes the green square around the turbo light itself comes on, usually when it is under load and on the skinny pedal real good. Couldn't find much on this anywhere. Thanks for the help.

PlaneDriver Posted October 19, 2013 Share Posted October 19, 2013 The green square outline is the only light. Your description of the square light sounds normal. There is no light behind the turbo icon itself. Link to comment Share on other sites More sharing options...
mtsinner7868 Posted October 19, 2013 Author Share Posted October 19, 2013 After looking at it closer that is the case. But what is that square green light alerting me to when it comes on ? Link to comment Share on other sites More sharing options...
-tombba- Posted October 20, 2013 Share Posted October 20, 2013 It lights up when the intake manifold pressure goes over the standard athmosphere pressure and the turbocharger starts making some boost. Link to comment Share on other sites More sharing options...
