Surf Ghost302 11 Report post Posted November 22 Currently finalizing an install of an AAW wire harness and VHX digital dash on my 1969 convertible. Everything has been pretty straight forward with a bit of trouble shooting. My current concern though is how to run the wire for the gas. Im getting a bit confused on the directions. "Use the FUEL - and FUEL SND terminals and run a twisted pair of wires back to your fuel level sensor. Connect the FUEL - terminal to the fuel level sensor body or a mounting screw to insure the sensor is sufficiently grounded. The other wire is the sensor signal which goes to the FUEL SND terminal." Since the AAW harness already has a wire run for fuel should I hook that in and make a short ground wire to come out or do I ignore the AAW fuel wire completely and custom make a twisted pair all the way back to the fuel tank. Current fuel system is OEM. Nothing special. I havnt tried calling dakota digital yet. Wanted to see if anyone knew of another post that may have gone over this or had any good pointers. Honestly if anyone has a full write up of installing a VHX to an AAW that would help to so I can cross check the rest of my work. This is the biggest undertaking Ive done so far for electrical on a car. Thankyou! Quote Share this post Link to post Share on other sites
Midlife 838 Report post Posted November 23 The ground for the factory fuel sending unit is the chassis. Run the FUEL SND to the sending unit and ground the other wire somewhere conveniently, which could be in the dash board area behind the dash cluster.

det0326 192 Report post Posted November 23 The twisted pair of wires is to help with elctromagnetic noise for digital devices. If you can put the twisted pair in your new harness it sure can't hurt. Quote Share this post Link to post Share on other sites
70Boss351 5 Report post Posted November 24 I also have Dakota Digital gauges and American Autowire and I used the AAW fuel sender wire and added a new black ground wire from sender to DD interface. It wasn't twisted together but has been working fine. Quote Share this post Link to post Share on other sites
kblagron 28 Report post Posted November 25 I didn't add the wire for ground, and all is fine. My recommendation - if you can do it, but, at least for me, it will probably work fine. Quote Share this post Link to post Share on other sites
Surf Ghost302 11 Report post Posted November 25 Thanks everyone! I ended up running a ground all the way back to the fuel tank. AAW and dakota both confirmed what everyone here said. It could be run all the way back or just grounded up by the module. I appreciate all the responses. 1 kblagron reacted to this Quote Share this post Link to post Share on other sites
