gauge wiring help

[foxbody89lx]

ok here goes, i'm installing a Fuel Lever , and Electric Oil Pressure gauges in my car. it's a 90 Mustang GT.

Now from the Fuel gauge i ran Grnd terminal to Grnd, Ignition Terminal to Red wire/ Light Green Stripe ( behind speedo Gauges ) , and the Sender Terminal to the Yellow/White Stripe wire ( behind speedo ) and get nothing. checked ground it's perfect.

Now the Oil pressure gauge i ran Grnd terminal to Grnd, Ignition Terminal to Red Wire/ Light Green ( like above ), and the Sender wire to the new Sending unit i installed, again nothing.... please help a brother out. thanks

if you are sure your conection to ground is good, you might want to make sure that the power wire is hot in the run position. Not trying to be a smart a** but, I once tried to hook some stuff up & tapped into a wire that only had power in the start position. another time on a different vehicle I almost tapped into a wire that was hot all the time. just something to check. might look for a blown fuse or something too. make sure sender & power wire aren't crossed at the gage. thats about all i can think of. hope it helps.

I agree. Use another fused power source and ohm out your grounding point.

Good luck.
