gregs89oldscutlass Posted March 6, 2005 Report Share Posted March 6, 2005 I want to add the Trip computer to my 89 Cutlass Supreme International Series and am in need of a wiring diagram. My service manual doesn't have the actual wiring diagram just on how to diagnose problems with it. Thanks, Greg Quote Link to comment Share on other sites More sharing options...
pitzel Posted March 6, 2005 Report Share Posted March 6, 2005 Wiring? It should be pre-wired just waiting for you to plug the DIS in. Quote Link to comment Share on other sites More sharing options...
GutlessSupreme Posted March 6, 2005 Report Share Posted March 6, 2005 Yea, an International should be prewired. If you have Digital Climate Control, they harness should be there for sure. Odd that your manual doesn't have a diagram though.. should have details to the extreme This should help: http://www.w-body.com/forum/viewtopic.php?p=260798 Quote Link to comment Share on other sites More sharing options...
pitzel Posted March 6, 2005 Report Share Posted March 6, 2005 Just out of curiosity, what exactly does the manual say about diagnosing problems? For some reason, my fuel level sensor is perpetually stuck on 99%, and my miles counter/'DEST' function hasn't been working. Everything else works though, so obviously the VSS isn't broken, and I can't imaging the fuel tank sensor having anything to do with the trip meter functions. Loose solder joint maybe in the DIS itself? Quote Link to comment Share on other sites More sharing options...
