kook911 Posted December 22, 2017 Share Posted December 22, 2017 So I got tired of not having a speedo or mileage, so I finally got around to do some looking the problem. Well it didn’t take long but I found it and now need some help. The wire that comes off the transfer case is not connected. When I did my swap I guess I never hooked it up. So can someone tell me where this wire hooks into? I don’t know if I even have it on the correct side. This is where I zip tied it and left it.

Eagle Posted December 22, 2017 Share Posted December 22, 2017 What year MJ is this for? If this is for the '87 in your signature, your speedo is mechanical, not electrical. Link to comment Share on other sites More sharing options...

So I’m electrical speedo but I don’t know where the plug plugs into. Link to comment Share on other sites More sharing options...

HOrnbrod Posted December 23, 2017 Share Posted December 23, 2017 The speedo connector (among other wires) on the 91 is on the right firewall circled in red below. I don't know what engine harness you have. Image3.psp Link to comment Share on other sites More sharing options...

Got it corrected and we are good to go now. Thanks for the help Link to comment Share on other sites More sharing options...
