Hi, I put together one of the transistor/capacitor 5V convertor tricks for my gauges.
I hooked it up as in this picture with the input pin attached to the red wire, and output is the orange wire. It puts out 5V. WHen I installed it, I get nothing. Guages were tested and work. Two possible reasons it does not work:
1) I have the blue ground wire going to the steering wheel support, not the pot metal of the dash cluster.
2) Dash cluster also has a ground wire going to same point on support. Ground is ground, so I think I'm OK to discount this reason
3) WHile I did put some red shrink wrap on the terminal at I (red wire connection), I used a metal speed nut to hold down wire. Maybe I need to use a rubber washer before putting on speed nut?
4) You tell me.
THe regulator inside gas gauge is disabled.
THanks for looking.
