do you plan on plugging it into the connector that goes into the printed circuit, or straight up to the fuel gauge

if you want to use the printed circuit, use this picture

yea i just want to connect strait up to rear of fuel gauge ,cause the tabs that are for the fuel on the curcuit are all gone ,they were distroyed ,the only ones cause the rest i cleanup good & are working ,,,thanks

i think positive wire goes to post A on my diagram ,negative wire on B ,& the sending wire unit on C , i just want to get them strait or else ill end up burning the guage which is new ,,,thanks

You can check this link and I think you will find that the connections are as follows.

A. Is the sending unit
B. Is positive.
C. Is the gauge ground.

Here's a cluster diagram showing the wiring.



It doesn't show the ground but it's there.

Just out of curiosity, which connector is which on the back of the fuel gauge.
