Wiring issues

[jim1131]

Working on my butchered instrument cluster wire harness on my 1165 with electronic speedometer and traced most of the wires and marked them with the correct numbers. A few wires are not shown in the manual and im looking for some help on these. Basically 2 cut wires attached to my cluster with tag numbers 58H & 58E but can't match them anywhere on the harnes, im assuming they are ground. Also not sure where 40W plugs into, any help will be appreciated.

58e temp guage
58h fuel guage

the dash diagram is on around page 2999 of TM 9-2320-387-24-2.

As Action said.
They are grounds

I looked at the wiring diagram for the 1165 with serial number below 300000 and couldn't find 40W, not even on model other diagrams.

The 40 circuit is gauge lighting. It’s probably part of the 80 mph speedo and would plug into a splitter from one of the two dash lights.

40W is on one of the 2 Y harness for speedo system
