ruralandalone Posted July 4, 2018 Share Posted July 4, 2018 Can anyone tell me exactly where this is located? Quote Link to comment Share on other sites More sharing options...
Ωhm Posted July 4, 2018 Share Posted July 4, 2018 Both 2.5L & 4.0L show B/U switch located on the transmission. 2 pin connector. Add your vehicle stats to your signature. Quote Link to comment Share on other sites More sharing options...
ruralandalone Posted July 5, 2018 Author Share Posted July 5, 2018 Thanks for that. I think I did add a description to my signature, but in any case its an 86 with a 2.5l Quote Link to comment Share on other sites More sharing options...
Ωhm Posted July 5, 2018 Share Posted July 5, 2018 2 pin connector is for a manual trans. NSS (gear selector switch) is for the automatic, located on the transmission. Quote Link to comment Share on other sites More sharing options...
ruralandalone Posted July 5, 2018 Author Share Posted July 5, 2018 I think I found the problem. Looks like there is a short and break in the wire to the backup lights in the harness that runs from the fuse box are to the back of the cab. On a related note, why don't I have a TCU fuse circuit in my 86, even though there is one marked on my fuse panel? Quote Link to comment Share on other sites More sharing options...
Rockfrog Posted July 5, 2018 Share Posted July 5, 2018 Because you had a non electronic auto, only the AW4 used the TCU. The A904's were "dumb" as it were. Sent from my SM-G930W8 using Tapatalk Quote Link to comment Share on other sites More sharing options...
