markg Posted May 6, 2008 Share Posted May 6, 2008 Can anyone help me out of my puzzle with this red (lighted when switched on) toggle switch? What is it for? It looks original and is located just above the hood release lever. It's on an 87 Dolphin 900 version. The owner's manual call it a "rear deck light" but I think that's just for a pick-up only. Thanks much in advance. Mark@phch.org Quote Link to comment Share on other sites More sharing options...
knowltondata Posted May 10, 2008 Share Posted May 10, 2008 The 4runners had a rear deck light switch it was black with a red/orange lighted circle on it. The trucks didn't have bed lights. Quote Link to comment Share on other sites More sharing options...
markg Posted May 10, 2008 Author Share Posted May 10, 2008 Now that's an interesting idea about the rear deck light... that's what my owner's manual calls it, too... Could it be for a light that illuminates the RV/motorhome inside which is activated from the cab at that toggle in question? Anybody have an RV light switch that can be turned on from the cab? Thanks! Mark Quote Link to comment Share on other sites More sharing options...
markg Posted May 10, 2008 Author Share Posted May 10, 2008 Figured it out (I think).... What it (red lighted toggle) does is ground out (through the lighted toggle) the blue (hot) lead coming into the transmission relay. This would have the effect (I presume) of defeating that relay which I suspect is linked to the high altitude sensor. Also, on closer inspection, the toggle is definitely after market and the transmission relay is stock. So someone wanted to be able to defeat the high alt sensor with the flip of a switch. I'll confirm thins on my first trip over Donner pass in a couple months. Does this make sense to you tech folks? - Or am I off base here? thanks, Mark Quote Link to comment Share on other sites More sharing options...

Langeman Posted October 15, 2009 Share Posted October 15, 2009 Could it possibility be for after market fog lights that have been added? Quote Link to comment Share on other sites More sharing options...
Bodybagger Posted October 17, 2009 Share Posted October 17, 2009 Hate to be the one to say this, but you should trace the wire from the switch to whatever it is connected to in order to be certain. Quote Link to comment Share on other sites More sharing options...
