Cool electric oil gauge 73gmc

the gauge needle is at 3'oclock. pin #6 is being used by the oil gauge and the temp gauge. the temp gauge works but not the elec oil gauge. pin#6 is attached to the oil sender wire, pin#5 gets ign power from the power gauge wire. thanks for any help. for your info this PCB is from an 89.

Re: electric oil gauge 73gmc

73 doesn't use electric oil gauge, it's mechanical.....

Re: electric oil gauge 73gmc

hi b454rat, is it still mechanical with oil sender. i know the hookup for the mechanical oil gauge. this PCB does not support an oil mechanical gauge, it is setup for an electrical wire hookup. thanks

Re: electric oil gauge 73gmc

hatzie this cluster is from an 89 gmc, bought on ebay. i know most things work on 73 and on. my problem is the elec oil gauge sits a 3'oclock. it is properly grnd. we are talking about 2 wires on the clustr plug. the gauge uses 3 metal contact clips on the cluster 2 for power 1 for grnd. hookup is the power wire from fuse bx is attd to 1 wire, the other to the sender wire. i could take a pic of the cluster if needed. hope this helps.
