nwenzel Posted August 28, 2020 Share Posted August 28, 2020 I just picked up a 93 Loyale and it runs. A little rough but it runs. While looking things over notice there are 3 wire harnesses not plugged in to anything by the fuel filter. Anyone know what they are for?

DaveT Posted August 28, 2020 Share Posted August 28, 2020 The single pin white and green ones are for various ECU test modes, leave them disconnected. The bigger one is for a diagnostic tool to plug into. 2 Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 28, 2020 Share Posted August 28, 2020 Cars in general have MANY unused plugs. They are there for various reasons - usually diagnostics or options that model wasn't equipped with. GD Quote Link to comment Share on other sites More sharing options...
